Sorry it's taken so long to respond to you. I've had 3 crashes to recover from.
My Ernst Baier(Beyer)was married to a Marie in MN. It might help if you had a general area where they might have been born, lived, or were married, and a time frame for any of those. Search sites about the areas too.
As I have found out, Baier is as common as Smith. You may have to get more info from death, marriage, and birth certificates or notices in order to narrow your search.
It could be that we will connect later as I get more info on this difficult line.
