Above is a picture of Dennis and Katherine Leary. Dennis and Katherine were the parents of three children that I know of: Walter, Arthur, and Agnes. Walter was my great grandfather and the father of Helen Keenan (nee Leary).
Dennis was born in Canada, but his father Cornelius was born in Ireland. It was pretty common for Irish immigrants to come through Canada, so I assume that Cornelius and family did that, stayed in Canada for at least a little while before coming into America via upstate New York. I have heard it told that Dennis didn't like mentioning - and maybe even outright denied - that he was born in Canada. So even back then people didn't like to admit that they were from Canada.
I don't know exactly when this picture was taken, although I will hazard a guess. Dennis lived to be 80 years old, Katherine to 75. If we guess they are maybe 65 or 70 years old in this picture, it would put it around 1900 (give or take a decade).
