I realize your post is quite old, but I only just started researching. Paul R. Hadley, son of George Fremont, was my husband's grandfather. I know his obituary says he was born in Broadalbin but some newspaper articles say DC and certainly he lived in DC for some time. His obituary (the one on find a grave) lists his parent as Manning and Catherine. There were a Manning and Catherine Hadley in DC in the 1870s . So I am thinking that's his parents and I dont know if they had moved there from Broadalbin or if Broadalbin was a mistake. Anything you know I would love to hear! My tree (hadleyiii) is public.
