Their son, John W. Payne married 14 Feb. 1916. John's age is estimated to be 70 in 1916. So, he was born about 1846. I assume that his mother must have been born between 1800-1830, but where?
Would you know where Sarah Pulliam lived before the move to California and can you estimate a birth date and where she was born? This could help narrow down where to search for her parents and what time frame to look at.
