Anne: I show two Anson Geigers as great grandsons of Hans Ulrich. One is the Anson Butler mentioned earlier, son of Abraham Harroll, but he was b. 1854. The other was the son of John Martin Geiger and Emily Joiner. He had a sister named Mary. Is this your Anson? I don't have any dates for either of the children of John Martin and Emily. In answer to your question, no, I have not done any looking for the unusual names in this family, but it is a piece of work that someone needs to do. They don't appear to be very common names. Regards, Warren
