Just caught your listing for information on Hattie C. Briggs on genform.
You are off to a good start.You are correct; her parents were F.M. (Francis Marion) Briggs and M.A. (Mary Ann Ludwick).F.M.'s father was James L.; mother was Ann Manly (Manely).You will find them in Lafayette County, Mississippi from 1840-1870(-).
F.M. is my great grandfather.O.B. (Other Bourbon), Hattie's brother, is my grandfather.
F.M. and M.A. are buried in Picton, Texas along side Emma (Hattie's sister) and Jim Skinner.Two of Hattie's brothers are also buried at Wheatland (James E. and Daulty Mansfield), as are a number of the Briggs clan.
You may know all of the above; if so, just disregard this.
