Information from Joel Barger:
ISAAC BARGER, son of Simeon and Sarah Jane Fisher Barger, was born C. 1780 in Berks County, Pennsylvania. He married Polly Collance on 05 Feb 1809 in Lincoln County, North Carolina. Polly burnt to death on 22 Feb 1838. Isaac sold out his lands sometime after this and moved to Jefferson County, Alabama where he died in 1845, or shortly there after. Henry O. Barger is the main Genealogist for this line.
Note: New information about Mary "Polly" Collance/Collins. She did not burn to death, it was a daughter of Jesse Barger. Further, Isaac had moved to Jefferson County, Alabama by about 1821, not 1838 (see census records below).
Note: Henry O. Barger found the record of their marriage in "Book of Marriages of Lincoln County, North Carolina" -- The witness of the marriage was George Seitz and vows performed by Mic Cline.
