OK - I've been doing some intensive searching for the past week but can not find anything going back before Edward Osler and Joan Drew which is my goal at the moment. There is a page with a tree made by Percy A. Bath here... http://freepages.genealogy.rootsweb.ancestry.com/~bathonia/O...
(I can't find who posted it but my sincere thanks go to the poster for all the hard work it must have been)I have received a reply back to a request to Hamilton Public Library for an original copy (the stated source on this page) but they are unable to find it. Most of the information seems to tally with information I've already plugged into my database from other sources however so useful nevertheless, although there are no sources mentioned and most certainly a few errors here and there (perfectly forgiveable for a tree made in 1937 when there was no "internet"!)
The Royal Canadian Air Force have been very helpful with providing me with info and pictures of Oslers who were members as has the Royal Military College of Canada but these only include post WWI Oslers.
Anyone know anything on Jamie Osler (must be about 55 now if still living - son of Edmund Boyd Osler (1919-1987) (AKA "E.B.") or "Gordon Peter Osler" (b.1922 d.??? - may be still living aged 90)?
