Looking for info on Gilbert Kellum, born ca. 1797 in Virginia. Married Elizabeth Hall in Dubois Co., Indiana ca. 1820. Elizabeth born ca. 1797 in Kentucky, daughter of Edward Hall & Rachel Barnes.

2) Reason, born ca. 1825. Married Sarah Ann Osborn Nov. 27, 1845 in Bureau Co., Illinois. Reason and Sarah had 2 children, Eliza and Henry.

Elizabeth Hall's brother, John Hall, married an Elizabeth Kellum. She was born Oct. 16, 1803 in Kentucky and died November 9, 1875 in Atchison Co., Missouri.

Elizabeth might be a sister of Gilbert. Name is sometimes spelled Kellums.
