I recognize many of the surnames in your email from my matching trees. My family name is Meier, previously spelled Maier. Many of the Meiers I match in other trees are from Baden Wurttemberg although my grandfather Josef Meier was from Bavaria. His parents were Josef Meier and Rosina Raniznger, but that is about all I know about him. He became estranged from his family when he emigrated to the US in 1926 with his wife Maria Wagner. I believe that I also have Meiers on my mother's side. In particular there is a Wilhelmina Meier (born around 1799) who I think is on my other's side who married a Bruning. Please let me know if any of this matches up with your Meiers.
