My grandmother was Bertha Knipe Anderson, daughter of Joseph Farmer Knipe. Married to Amos Anderson, moved to Pittsburgh, Pa and then to New Kensington, Pa. They are buried in Union Cemetary in Arnold, Pa. They had three children- Lillian, in 1896?, Edwin, and my father named Louis Gilbert but changed to Gilbert Louis, b 8/26/09. We have a commission signed by, it think, Andrew Jackson and my cousin has one signed by Abe Lincoln. I have seen his dueling pistols in the museum after they were returned. I don't know anything about Bertha's brothers and sisters, or their mother, and the current generations. Any info would be greatly appreciated.
