Christine,
I read somewhere in your queries that you had a Regmann and a Zwahr. I have a Anna Maria Regmann that married a Carl August Hartmann and a Hartmann that married a Zwahr.
They were from Gröditz near Bautzen in Saxony where you state yours were from. My Hartmann/Regmanns settled in Austin Co. Texas in 1860.
Let's correspond. Verna
