What's Your Mix?

My English great grandfather David Simpson

It occurred to me a few days ago that I don't know my mix. By "mix" I mean the % of my ethnic ancestors I have in my bloodline. 

I know I have Irish, English, Dutch, American and Canadian but as to percentage of each group, I've never bothered to figure it out. So here goes!

I'm only going to go back 5 generations because that way every branch of my ancestors is known to me. I can go back 15-20 generations on some lines but not my Irish McGinnis family. I don't want to assume they are Irish going back from my 2nd great grandfather Joseph McGinnis. 

So - if I take my lineage back to my 2nd great grandparents, who's in the mix? And where were they born?

Paternal Ancestors:
3 born in Ireland, 2 in England and 3 in Canada
Joseph McGinnis & Fanny Downey - both born Ireland
David King & Mary Bell - both born England
Levi Peer & Jane Greenlees - Levi born Upper Canada (Ontario). Jane born Ireland
Isaac Vollick & Lydia Jamieson - both born Ontario. Isaac and Lydia's lineage is Dutch

Maternal Ancestors: 
8 born in England!
Charles Fuller & Georgiana Golding - both born Kent England
John Caspall & Mary Ann Williams - John born Kent, Mary Ann born Devon
Charles Simpson & Sarah Jane Page - both born Kent England
William Stead & Sarah Elvery - both born Kent England

Of my 8 great grandparents, 4 were born in Ontario and 4 in England
Of my 4 grandparents, 2 were born in Ontario and 2 in England
My mom and dad were both born in Ontario

Ireland = 3
England = 16
Canada = 11

I'd need to go futrher back to bring in my Dutch, German and Native American ancestors. 

The total is 30 so I can calculate what % of 30 each of those numbers is.  I do it with Algebra: 

We know that Ireland is 3 out of 30
So X % = 3/30
Therefore X/100 = 3/30
Next step is X= 3x100 / 30
Thus X=300/30
X=10

It looks like I am 53% English, 37% Canadian and 10% Irish. What's your mix?
