Hello, I was trying to do research on my grandfather trying to find out anything about his ethnicity (???) when I came across this post - Walter Dennis (Denis?) Shanahan, he was my grandfather. In fact today was the first time I've ever found a photo of him :) :) :) and his likeness to my uncles and mom is striking! As to your question I don't know a lot about the adoption itself, but just what I've heard about him in general (as I'd never met him) from my mother, which is not too much. He married my grandmother Anna Catherine Thomas and had 4 children, Dennis Walter, Michael Joseph, Patrick (ugh, middle name slips my mind atm) and Catherine Ann (my mother). It is also been my long time understanding that he was an orphan train rider, arriving here in Olmsted County from New York. I know it's not much but I hope that helps you and if there's anything else I can help with let me know.
