Well, we seem to have the same two surnames for our ancestors. There must be some connection.
Here is a great website for old records from that area.
I found many documents for my relatives. You can also
join the website, they have a forum. Maybe you can
contact relatives from there. The documents are in Russian or Polish. So far I don't know if my Mis ancestors had a son named Edward, but I'll let you know if I find something.
