After I posted this messasge a few years ago, I had a reply from a Jerry Frank in Canada who suggested I try this site:
http://www.sggee.org (Apparently it stands for "Society for German Genealogy.") Many of my family settled in Berrien Co., MI. It's confusing to read their naturalization papers, as they give different answers regarding their last foreign address: Gostynin, Russia; Salomka, Russia; Volhynia, Russia; and even The Republic of Poland. I believe all these are now part of Ukraine. The site would probably be helpful, however, there is a fee involved. I've not pursued it. Hope you are successful!
