Fleming Family Saga Jane Beatty Fleming, second oldest child of Laird Beatty Fleming and Jemima D. HODGES Fleming, was born April 23, 1817 in Jefferson County, Georgia. The story of Jane's Fleming ancestors begins with the arrival of her grandfather, William, in Jefferson County. William Fleming is likely to be the son of Samuel (The Sire) Fleming who immigrated in 1767 from Ireland to Savannnah, Georgia aboard the Hopewell, captained by Robert Beatty. William was born in 1750 in County Antrim, Ireland. (P.A. Adams)
