This is a Message Board Post that is gatewayed to this mailing list.

I agree that Obed Chamberlin and his three brothers must be descendants of Jonas(1) Chamberlain, perhaps the sons of one of his grandsons, likely either Gersham or Joshua, both of whom have large families with several sons born before 1800, per the 1800 Chester Co. Census. Joshua, for instance, appears to be the person listed in Sadsbury Twp., Lancaster Co. in 1810, 1830 and 1840, with William M(arsh) - Obed's brother - appearing there in 1840. A Jonas, age 50, appears there in 1850 also - I've not identified him. I'd be pleased to compare notes/data with you - please contact me via Email if you'd like. I maintain a file on this family on behalf of the World Chamberlain Genealogical Society.
