Carl Zyburski was the brother of my Grandmother, Helen who married Stanley Jakubowski in Buffalo in 1914. They moved to Detroit. As a child, I remember visiting the Zyburski's in Hamtramck. I have some information about his children. But still looking for any information about his son, John. I'd be thrilled to compare notes with you. Sorry I did't see this post sooner.
