I am researching the family of Adam Vogel,b. 1864 in Kremsdorf, Austria or Germany. His naturalization papers state he was born in Kremsdorf, Germany; however, I have been told that since he was Catholic it was probably Kremsdorf, Austria. I also believe his mother's name may have been Cunigunda which I am also told was not a name found in Northern Germany. How can I find out where to search for information on this Vogel family?
