Richard,
We seem to be related. Christian W. is my great-great grandfather. I am descended from his son Ernest Schroeder. I've recently tracked down some information from LDS records.

Friedrich Wilhelm Schroeder: no birth or death year given. His son was
Heinrich Rudolf Schroeder: Born 1781 and he married Louise Wilhelmine Voelling on June 5 1829 in Levern Prussia. His son was

Johann Heinrich Ludwig Schroeder: Born 23 Jan. 1829, Baptized on Feb. 1 1829 in Levern. He married Henriette Charlotte Wilhelmine Wernhardt on May 7 1858 in Levern. Christian Friedrich Wilhelm Schroeder was born to them on 20 April 1871 and was baptized on 30 April 1871 in Levern. Johann Heinrich Ludwig married his third wife Maria Charlotte Wilhelmine Klokke on Sep. 20 1877 in Levern. I wasn't able to find anything on his first wife yet.

I'll continue to dig further.
