Hi Trevor,
While I was out at the Library this evening, I went through the Ontario Marriage Index for your Charles Bagnall and found the following:
Groom: Charles P. Bagnall
Place of Event: Toronto, Ontario
Date: February 25, 1913
It's only an index, so I requested the microfilm that the original marriage registration is on which will show the bride and other information. It only took about 1 1/2 weeks to get, so I will let you know when it comes.
Also, my sister is going to check with one of the Doctors she works with who is into military history, so perhaps he may shed some light on the "Military Hospital" in Guelph.
Karen
