My grandmother, Nadja Scheidemann, was born in Poltava, Ukraine on March 4, 1880. Her parents were Eugen V. Scheidemann and Helene Grinewitsch.
My grandmother married Rudolph Prenzlau in 1905 and moved to Latvia. My mother, Benita Prenzlau, was born in Ventspils, Latvia.
I believe that both the Prenzlau and Scheidemann family lines originated in Germany.
I would like to know if anyone is familiar with these names and has knowledge of their history.
