Hi Valerie,
I could not find your post on the Great War Forum, so I don't know if someone there already told you about this, but you can view the attestation (enlistment) papers of all soldiers who served in the Canadian Forces in WWI at the Library and Archives of Canada:
http://www.collectionscanada.ca/archivianet/02010602_e.htmlThere were more than two dozen Frank or Francis Taylors. Some of them died in the war, so you can rule them out - you can find the list of men who died at the Canadian Virtual War Memorial
http://www.vac-acc.gc.ca/remembers/sub.cfm?source=collections/virtualmemThis will give you their service number, so you can match it up with their attestation papers at the Archives site. I would think you could also rule out the ones who were married when they enlisted, but I guess you never know....

I sometimes go to the Archives for my own research. I would be willing to look through the service records of the Frank/Francis Taylors for clues. If he went through the Kinmel camp it should be recorded in the file, and would give the specific dates he was there. (The enlistment papers posted on-line are only one part of what's contained in the soldier's file).
It will take me several months to get through them all, because I don't go all that often and I would be doing other things at the same time, but I'm willing to give it a go!
If you would like me to give it a try, could you do a bit of the ground work and send me a list, with name, service number and box reference number of the most likely "candidates" to search first? (ie: lived through the war, unmarried, check all Franks before searching Francis, any other criteria you wish to use...) That will make my research a bit more efficient. A specific date range when you would expect him to be at Kinmel would also be useful.
Send me a PM if you're interested and I'll send you my e-mail address.
Martha
