Looking for Descendants of Mutiny on the Bounty Mutineers

HMS Bounty List of Mutineers
Here's an interesting DNA story. Phys.org writes that
"Ten pigtails of hair thought to be from seven mutineers of "Mutiny on the Bounty" fame and three of their female Polynesian companions will be analysed in a new collaboration between the Pitcairn Islands Study Centre at Pacific Union College (California, US) and the forensic DNA group at King's College London (UK)."
Since there are no hair roots in the saved pigtails, Y-DNA is not possible which means DNA analysis will not be able to trace male ancestry of the pigtail owners. However researchers are hopeful that mitochondrial DNA can be extracted. This will provide details of their maternal ancestry.

The pigtails on display in the US were housed in a nineteenth-century cylindrical tobacco tin. Also with the locks of hair was a handkerchief said to have belonged to Sarah, the daughter of William McCoy, one of the Bounty mutineers.
A worn, faded label with the pigtails notes that it is attached to the hair of William McCoy. The mutineer McCoy died on Pitcairn Island in 1800. Notes written on the label also state that the pigtails are of seven of the mutineers of H.M.S. Bounty and "also that of three of the Tahitian women," who accompanied the mutineers to Pitcairn in 1789.

Baby Boy Hacht - Dead, or Kidnapped and Alive Today??

"A baby boy who was never named was born in July 1944, in Detroit, Michigan.  The family believes that he was kidnapped and another dead baby substituted for Baby Boy Hacht.  While at first this sounds improbable, if not incredulous, it isn’t." Source:DNAeXplained – Genetic Genealogy
Baby Boy Hacht's sister Patti and her brothers are looking for answers through the use of DNA. You, or someone you know, may be the key to this puzzle.

"The Y DNA of Baby Boy Hacht or his male child or male grandchild through a son will match that of Patti’s brother.  The autosomal DNA of Baby Boy Hacht or his children or grandchildren of any gender will match with Patti and her family." Source: DNAeXplained – Genetic Genealogy

DNA links 5,500 year old remains to 200x Great-Grandaughter

This is an exciting find for scientists who studied DNA from various individuals in an attempt to match them with four very old skeletons found previously.

The study used DNA samples from 60 modern members of the indigenous Tsimshian, Haida and Nisga’a tribes from the Metlakatla First Nation for a study.  The samples were compared with mitochondrial DNA extracted from the teeth of four ancient people: two skeletons aged 6,000 years and 5,500 years unearthed in an ancient shell midden on Lucy Island, and two skeletons aged 5,000 years and 2,500 years found on Dodge Island.

Three living individuals had DNA matches with the older Dodge Island skeleton, and three of the skeletons matched at least one living person.  The oldest Lucy Island skeleton didn’t match any living relatives, but did match a 10,300-year-old skeleton previously unearthed on Prince of Wales Island, Alaska.

Six Generations of Strong Females on International Women's Day

Six Generations of Strong Females on International Women's Day

Today is International Women's Day and to celebrate I am sharing a collage of 6 generations of my direct maternal line. It is wonderful to have photos of our direct female lineage back to my great-great grandmother Sarah born in 1836.

Starting from the left we have Sarah Stead, my great-great grandmother. Next is Sarah's daughter Sarah Simpson, my great grandmother. Then we have Sarah Simpson's daughter Ruth Fuller, my grandmother. Then comes Ruth's daughter Joan, my mother. Then me and then my daughter Judy. Then our direct maternal line is done as my daughter had sons but no daughters.

My maternal DNA has been tested and shows that I am Haplogroup J2a1a1b . My DNA shows my origins as Irish, British,  French, German, Scandinavian, Northern European, East Asian and Native American.

Have you tested your MtDNA? It's interesting and fun to do that!

Understanding Your DNA Results: Comparison Charts

DNA is the latest genealogy tool and I've had my DNA tested with 3 different companies now (with one more pending). I used Family Tree DNA, 23andMe.com and DNA-me for testing. Since I'm a woman I can only test my Mt-DNA or my Autosomal. I have to leave the Y-DNA tests to a male relative. 

DNA results are not easy to understand and I don't pretend to understand them very well at all. So what I have done is make a spreadsheet of the summary of my DNA results - the Haplogroup I am in, my genetic origins and my percentages of various ethnicities. 

Each test is likely to show different results depending on the number of markers that were tested and the algorithms used to interpret the test. So I expected to find some differences but that is what makes testing with more than one company worthwhile. In fact it's important if you want to understand your DNA in more depth.

Definitions

You also have to do a lot of reading (aka research) to increase your knowledge of DNA testing, the various tests and what the results mean. What I have gleaned (admititily just the tip of the DNA iceberg!) Is this: 

MtDNA - Maternal DNA is passed from mother to child (of either sex) and does not change over the generations. A female testing her MtDNA is testing her female lineage from herself to her mother to her mother's mother and so on. This is the X chromosome

Y-DNA - Paternal DNA tests the Y chromosome which is passed, unchanged, from father to son. Thus if you wish to test for your surname and you are a woman, you must find a male relative with that surname to take the test. Women do not have the Y chromosome (We are XX while men are XY)

Autosomal: Autosomal DNA recombines with every generation and that means the number of markers you share with a common ancestor is halved with each generation. 

Haplogroups: The Haplogroup your DNA indicates you belong to will show your deep roots, your heritage going back thousands of years.  

This is very basic but it's a start to understanding. There's no sense paying money for DNA tests and then just letting the results sit there because you don't understand what was tested or what the results mean.




My DNA Test Results

Here is the chart I've finished which shows the comparison of the 3 companies whose results are in. My 4th company is still running my DNA samples so I don't have that yet.


Family Tree DNA is the one marked as FT DNA. They do not narrow down my ethnic origins as much as 23andMe.com but you can see that they both agree the majority of my ethnic origins are European of some sort. 

DNA-me is the surprise with their finding of a smidgeon of African origin. And their Haplogroup assignment of JT also throws me a bit. I have more research to do to try to understand how that happened. I am pretty sure they didn't test very many markers and the more markers tested, the  more accurate the results.

You can also see that 23andMe.com has both Standard (75% accuracy) and Speculative (50% accuracy) results so I included them. The East Asian was interesting especially when I compared my test results to my brother's. Since his tests include the full Y chromosome testing there are bound to be some differences. And I love that 23andMe.com tests for your percentage of Neanderthal ancestry in your DNA! 

My Brother's DNA Results

For example even though we know we have Native American heritage on my father's side, it does not show on my results with any company. But it does show on my brother's results through 23andMe (but not Family Tree DNA) and on tests that Professor McDonald ran on my brother's Family Tree DNA raw data. Again this points out the importance of testing with more than one company. 



You can see that testing my brother's DNA confirmed our Native American heritage and the Asian heritage shown for me in both 23andMe and DNA-me testing. The big surprise was the Ashkenazi in his speculative results. It's important though to note that these results are only considered to have 50% accuracy. They may be correct but they are equally likely to be wrong. 

DNA Matches

I've also been studying and reading about how to compare raw data with matches found for me in each of the DNA company's databases. I'm getting better and can now narrow down the ethnicity we share (based on what chromosomes we match on). This obviously helps with figuring out who our common ancestor might be, but I have much more to learn. When I have that a bit more figured out I will post here. 

Meantime if there are any readers who understand what I've posted today better than I do (or better than my explanation) please do leave a comment so we can all learn from each other's knowledge.

23andMe DNA Test Kits Arrive

Olive Tree Genealogy: DNA Tests from 23andMe
My 23andMe DNA kits arrived yesterday. I ordered three - one for my brother (for Y-DNA), one for me (for mtDNA) and one for my husband (for Y-DNA)

We've already had our DNA tested at Family Tree DNA but we wanted to try another company and see what kind of results we get. 23andMe focuses on genetic health issues and that's intriguing. But I'm also interested in their

Previously I have written about my brother's Y-DNA results from Family Tree DNA
at Family Finder Test Results in for my Brother's DNA! His Predicted Haplogroup is I-M223.  Quoting from the website, this Haplogroup
"...has its roots in northern France. Today it is found most frequently within Viking / Scandinavian populations in Northwest Europe and extends at low frequencies into Central and Eastern Europe."
 
It's been really interesting reading up on this and finding out more about our McGinnis paternal line ethnic origins, especially since my brother's Y-DNA showed a mutation that scientists know exactly where and when it occurred! Turns out it was around the time Hadrian's Wall was built between England and Scotland and his gene mutation is known to have come from a group of Basque at this time.


I also had an exciting update on our results for Native American heritage, which you can read about at Update on DNA Testing for Native American Heritage

My mtDNA results from FT arrived and I wrote about those at mtDNA Test Results Arrived!
My Haplogroup is J2a1a1a2  but I still don't completely understand my full results.

I'm hoping 23andMe will provide more interesting details. 

Follow along with me as I get ready to provide the test sample and mail it back to 23andMe

DNA and Native American Heritage

I'm a recognized Metis in Canada. I have my official Metis card. But I have always wanted confirmation of my Native American heritage through DNA testing.

Now perhaps it is just me but for the life of me I cannot figure out on Family Tree DNA how to do this! I have my brother's Y-DNA testing done and have the Family Finder upgrade. I have my mtDNA done. I've been willing to pay for whatever upgrade or test I need. But what one?

I wrote to one of the partners in Family Tree DNA a week ago to ask for assistance. No response. I should add that I'm linked to him on Facebook and I've seen him online several times since I sent my message. I'm sure he's a busy guy but c'mon - a week goes by and he doesn't answer a customer and someone he's linked to on Facebook as a friend?

So on the weekend I posted on the Family Tree DNA Facebook page, and asked for advice.  Again my post was met with silence. No official response at all.  Thankfully one person responded and gave me advice and a contact name of someone not involved with FamilyTreeDNA who might be able to help. I plan to follow that up as soon as I figure out how to download my raw data from FTDNA site!

In the meantime Roberta Estes was recommended as the person to consult. She responded to me with a link to her blog post called Proving Native American Ancestry Using DNA According to Roberta I need to order an upgrade to test at D9S919. Her article went on to explain exactly how to order this upgrade on FTDNA. I am so impressed! That's the kind of help I like - a clear explanation and set of instructions that are easily followed.

So I've ordered the upgrade on my brother's DNA and on mine. We'll see what happens!

But I must add that I'm very disappointed in Family Tree DNA's lack of response to a customer. It's not only bad customer relations, it's bad marketing! I want to spend money with them and they are not bothering to help me do so.

Thank goodness for the willingness and kindness of strangers who jump in and try to help!

Is it Richard III's Body? Canadian's DNA May Be the Key

Researchers at the University of Leicester are currently analyzing bones discovered during a recent archaeological dig to determine if they are the remains of King Richard III, a 15th-century ruler of England.

Archaeologists had long sought the monarch's grave, which had been the subject of speculation for centuries. The recent discovery of a skeleton showing signs of Richard's famed spinal curvature and bearing signs of fatal battle wounds, however, isn't enough to solve the mystery.

A Canadian family who can name the king as one of their direct ancestors is providing the DNA evidence that will conclusively prove whether the remains belong to the late monarch.
 
Jeff Ibsen said his family contains a direct genetic link to the king with Ibsen's mother being a descendant of King Richard's sister.

When British historians established the ancestral connection nearly a decade ago, Ibsen said the family was warned that they may be pressed into service if the king's burying place was ever discovered.

Mitochondrial DNA is passed through the female line, and all the sons and daughters of the mother inherit her mitochondrial DNA.

Taking My MtDNA Test - Step One

Two years ago I had my brother's Y-DNA tested. I chose Family Tree DNA as they have the largest database for comparison purposes. I haven't written about my experiences with Y-DNA testing (all good!) but I will in a future blog post. Briefly, the 37 marker test allowed us to connect with others and eventually find our McGinnis ancestors place of origin in Northern Ireland. Only men can take the Y-DNA test which follows the paternal line unbroken from son to father.

A few weeks ago I decided to do three things - upgrade my brother's Y-DNA to a 67 marker test, order the Family FInder Test for Y-DNA and test my own MtDNA.

Both men and women can take a MtDNA test which follows the maternal lineage. I ordered my MtDNA test from Family Tree DNA and it arrived a few days ago.

When your kit arrives it has a Collection Number (your own unique ID), a welcoming letter from the head of the company, a page of easy-to-follow instructions, a return envelope and a plastic baggie with 3 collection sample tubes, 3 collection brushes and a permission slip.

Signing the permission slip is important as that allows  Family Tree DNA to compare your sample with others in their database and inform you of matches.

 I was excited to begin and read the DNA Collection Method. Basically it said I was to collect 3 samples several hours apart, by scraping the inside of my cheek for 60 seconds each time.

The only problem for me was that you have to wait a certain number of hours between scrapings as well as a certain number of hours after eating. Since I'm a "grazer" (I eat small amounts frequently throughout the day) it was difficult for me to figure out when I could get the samples.

Then it dawned on me that all I had to do was take Scraping #1 first thing in the morning, then Scraping #2 last thing at night and Scraping #3 first thing the next day.









 Scrapings done (easy!), permission slip signed and my test was back in the envelope ready for mailing. Now I wait. I don't know when I will hear from Family Tree DNA about my results but I'll post about it here on Olive Tree Genealogy blog when I do.
