My GG-Granfather, August Harder, who emigrated from Wismar to Arkansas writes in his journal of a C.F. Harder of Yates Center, Kansas.He believes that C.F.'s grandfather and his grandfather were brothers based on a letter he received in 1891.He also writes of a cousin Albert Harder of Iola, Kansas.
I have an uncle and cousin who are also reasearching the family.If we find a connection, we'll share it with you.
If you think there is a connection with my family, please send information to me at firstname.lastname@example.org.
