In Blair county PA, there was a family named Ketner who had a Martin in that family.
I would like to have some more information, maybe I can help you.
When I started many years ago, I knew nothing other than my grand father was born in Il, and, my great grandfather in Indiana. Now after all of these years I have a fairly large data base, give me what info you can, and, I willtry and help you.
My family came from Baden Waldangellock Germany in 1733 to Pa Family of six. Now we are many many ketners .
Any kind of info might help me some. Thanks Lois Ketner Angel
