Jelle (Charles) Posthumus m. Aaltje Pieters de Jongh Apr 20, 1885. They had ten children. He died on Mar 22, 1941. He is my 2nd Gr. Grandfather. I also need his ancestors, but have a lot of information put together by one of their daughters (my GR. Grandmother) Elsie. If you, or anyone else would like to exchange info, please let me know.
