I am the person in England who was searching for the information regarding Magloire Mercure back in 2007 on behalf of a friend. Magloire was my friend's grandfather, who married in 1942 in Surrey NW, had 2 sons Kenneth and Raymond in England, returned briefly to Canada ca 1947/8 where he had at least one daughter, (another may have died in infancy) and then returned to Surrey where he had twin boys and possibly another son?
I have also found a post on Ancestry message board relating to Raymond T Mercure from Australia.....
I don't use this site regularly and am therefore not au fait with its workings, but Magloire's grandchild would very much like to be put in touch with his second cousin gaetb6. Neither of us use My Heritage website.....but I have a copy of the family tree on my computer, but obviously names of the living are involved here.......
