Thanks Don for the response. The timing of the GP you referred to (b. 1824) would fit as the father of my Great Great Grandfather GP, and also fit with Shirley Baden's reference to a son GP b. 1849. However, she lists her GP as dying in 1936 in Newcastle, ME, which must make him a different GP than mine who died in Oakland, CA. Do you know if the Pinkham name is Swedish, or otherwise where it comes from?
