I am just starting to trace my ancestors, but was fascinated with your posting. My great grandfather Heindrick Herman August Dieckmann was from Germany. I was told he married Joanna Keizer(from the Netherlands)and had seven chldren. They moved to the US when my grandmother, Cornelia born 6-10-1896,was 15 years old. That would have been 1910 or 1911. From my limited knowledge Herman died at the age of 76. Is there any chance they are the same person or related? I was named after my grandmother. I can't wait to hear from you.
