I am still involved however, have not made it past Hiram and Phoebe either. These are my Wife's maternal family and the big goal at first was to get past her mother's father (she was born out of wedlock in the 1940's) Managed to get most of my information from someone whose wife also descended from Hiram. Afraid I cannot get you any further than what you probably see on the family tree posted. If you find any more let me know.
Thanks
