Hello, I believe that this is one of my ancestors. I have traced my history up to Philipp Burbach (Poorbaugh) who came to America in the 1700's. I have yet to find a definitive answer as to who his father was to continue my tracing back but I believe it to be Johannes Burbach > Adam Burbach > Johann Wilhelm Burbach > Heinrich Burbach which leads back to your family tree and information that you have posted. Could you share some detail as to what you know about the pre-1750's line of the Burbach family? Thank you!
