William Francis Cockriell (Frank, as his dad was also a William) married in 1919 in Elmwood, which is a neighbourhood in Winnipeg, Manitoba
I have the right surname and an area to check in now, and a fathers name, but a couple of cousins are saying her name was Elizabeth Constantine and not Constantia, all the info another cousin and I have says Elizabeth Constantia, I will have to get the birth certificate I reckon.
Just have to go back to that Canadian site and dig I guess. I will hang a pic on the end of this, of the young lady in question aged nine in 1907.
