I'm not a BELSER descendant but tracked a little of one South Carolina family as a sideline to the STAGGERS of Williamsburg District, SC.
Elisiph STAGGERS, daughter of wealthy planter, ferry operator and hotel-owner William STAGGERS of Kingstree, Williamburg Co., married William Mathis/Mathews BELSER of Sumter Co., SC, in 1854 in Charleston.
Wm. M. Belser committed suicide in 1859 (see death notice in SC newspapers of that date), and in the 1860 census, "E. S. Belser," female, age 23, (Elisipeth) was living withWilliam Staggers, age 80, in Williamsburg (her father).
If you have anything that connects to these people, do let me know.
