I hope you are still watching for replies.
I have been researching our families, and I believe my wife and you share a common ancestor - Anders Enegren, who was Clarence Enegren's great-grandfather. Anders was my wife's great-great-great-grandfather.
We knew virtually nothing about her Swedish ancestry until we began researching several months ago. We now have a great deal of information, some of which I'm sure you'd be interested in.
I hope you've also found out more since posting your note in 2002.
