Finding German records in the 1600's?
I have traced my main line ancestors back to the 1600's and now I am stumped to find any more information. The name Klingler comes from Germany. I am at Michael Klingler Sr. https://www.familysearch.org/tree/person/details/96XV-G3N. Although I am quite sure this person is the right person and his family and their families, I lack getting sources for him and his family. Can anybody suggest some great sources to prove my theory's for him and his family?
