I need all information I can on my great grandparents and their ancestors. My great grandmother left her husband when her kids were fairly young. I believe the only two that are the children of these two were my grandmother, Lois Walsh Crosslin and my Uncle Marty, I think his name was Martin James Walsh. I might be wrong on his middle name. They have half siblings, Jack and Rich Opray (not sure of the spelling). I can find nothing on my great grandma and I only know very little of my great grandfather other the he lived in Montana and his father was Thomas X Walsh. He possibly married twice. His wife I have seen listed as Mary Margaret and Mary.Both great grandparents claimed to be full irish. I found my Great granfather on the census and immigration listed as coming from a free state in Ireland. His wife is listed as irish as well. My great grandmother I know very little about and have nothing on her parents.
