Familysearch has a John Bigbea,s/o? b. 1755, Richland, S.C., f/o Mary Ann Bigbea,m. Sarah Marshall, b. 1757 in Lincolnshire, England, (d/o John Marshall, b. 1726, Lincolnshire, Eng. d. 19 Jan. 1801, Richland, S.C).If you find John's ancestors, please post them.I am a descendant of ACHSAH MARY BIGBY (BIGBEA?) b. abt 1775,d, abt April 1863 and Daniel Frederick Lucius (b. abt 1770, d. May 09, 1795. Both died in ANDERSON DIST., S.C. All I had was that Achsah's father was John Bigby, with no dates or birthplaces. If you are right in linking Achsah's father John to Judith and Sarah, those are more than I had found. Good hunting.
