I have a James Murphy B Abt 1807 in Loudoun, Va. (m) Nancy Jane Alden or (see above post) Anne H. Alder. Could possibly be a brother to your Amos. I don't have any information on parentage or siblings either for my James. Hopefully we can make a connection, even though the Murphy name is so common. Joseph Henry Murphy, son of James B 15 May 1833 in Richmond, Va. d. 08 Mar 1900 (m) Lydia Ellen Batten. Angeline "Angie" Murphy B 08 NOv 1864 in Pleasantville, Marion, Iowa, (m) Joseph F. Forst. If I happen to find more info on parentage/siblings that ties in I will let you know.
