Sorry it has taken me so long to rely. My Great great grand father was Wladyslaw (Walter) he was also born in German Poland in 1883 (April 19), he also owned a store in Detroit on Jos. Compeau it was a Sundries/candy and ice cream store. He was an only child but it is possible that they could have beem cousins. His parents were Peter Zakrzewski and his wife was Teofila (not sure on the last name). If any of this sounds familiar to you let me know.
