Recently the London & Middlesex County Branch Ontario Genealogical Society put a searchable index of 357,000 Obituary, Death Notice and Memorial records online. It's a great resource. I used it today and found several of my husband's Massey ancestors' obituaries.
It only costs $5.00 per obit if you can't make it in person, and at that rate, this is a very affordable way to do some long-distance research.
Here's the information you need if you want to order some obits after using their online index.
