Here is what I have about Tatum Gressett (Born March 13, 1831, Reevesville, SC - Died May 22, 1864, Atlanta, GA) Enlisted in 24th South Carolina Volunteers Jan 7, 1862 (unfortunately I have misplaced my notes on sources for this) His wife was Caroline Reeves (1832 - 1877)
Children that I know of were
William F. Gressett (Abt. 1857 - ?) Rachel Alice Elizabeth Gressett (April 12, 1858 - June 13, 1931) John Thomas Gressett (April 3, 1860 - March 20, 1944)
I have no information about descendants of William F. Gressett and have only one source that mentions him, (LDS genealogy records), so I have no independent confirmation of his identification as a child ofTatum and Caroline.
John Thomas Gressett (or possibly Gressette, at some point an e was attached to the end) married Rosa Emily Wannamaker.
I have two children for them, although there were certainly more: Furman Reeves Gressette Lawrence Marion Gressette (Feb. 11, 1902 - 1984)
Furman Reeves Gressette married Ula Mae Parker; I know of one child, Catherine Anne Gressette.
Lawrence Marion Gressette married Florence Howell; there was one child, Lawrence Marion Gressette, Jr.
Rachel Alice Elizabeth Gressett married Francis Mellichamp Weeks (July 27, 1859-April 26, 1950)
Children were Marion G. Weeks Dewey C. Weeks Caroline Elizabeth Weeks (1889 - ?) Albert Melishamp Weeks (is Melishamp spelling correct?)
There were at least three other children, but I have no names for them.
I have no information about the wife or descendants of Marion G. Weeks.
Dewey C. Weeks apparently never married; She was a schoolteacher.
Caroline Elizabeth Weeks married Earl Oscar Utsey (1886 - ?)
This is my complete list of descendants of Tatum Gressett.
