My computer is being repaired and along with the file with my Auction Photos. This is a photo from my family collection of my fathers side of the family. He is a WW1 soldier with no name and I do not know anything about him. The only WW1 soldier that I came across is Owen Mulroy, who was the son of my great grandfathers (Thomas Dowd) sister Catherine Dowd Mulroy. He died in 1918 from infection of war wounds. Owen is a possible candidate, but where did the photo come from and what is the number 2648 on the bottom of the picture?
