Thank you for the birth dates. I will see if I can find anything on them. Unfortunately Graham and "Charles William" are common enough names. Too bad he wasn't named "Zaphod Beeblebrox." :-)
By the way, did you also post a message about them in the message boards (General and others) for Manitoba? I checked and saw some messages about your McLean family line on the Manitoba > General; Manitoba > Winnipeg; and Manitoba > Interlake message boards.
I also scanned/looked through Manitoba message boards for the surname Graham. None of the messages seem to be about your Charles William Graham.
I'll let you know if I find anything that seems to be for your Charles William Graham and wife Emma (Emily) Mabel McLean Graham.
