Looking for information on Robert Pierson McMaster bn abt 1810-1811 and md Frances Jane BARNUM who was bn 1811-1812 in Ballston, Saratoga County, New York and dd 2 Aug 1844. They had: Rhobie, Elisabeth and Frances. Rhobie md George Lewis GILLESPIE.Any help greatly appreciated on parents, siblings, children, birth & deaths dates or places. I am working on the Rhobie/Rhoby/Roba/Rhoba/Rhobiagiven names and how most seem to relate back to Roger Williams of Providence, Rhode Island. I trace my given name back to 1715 as one of his grandaughters. Any help greatly appreciated. Thank you so much.
