There is indeed an Amanda Leeper,born Nov 22, 1877, died Apr 9, 1911 buried in the Leeper Cemetery, Mill Spring Mo., Wayne County.And she may well have been married to George Washington Leeper. He was not a son of William T. Leeper, ( he had no sons by that name in either of his two marriages)but was most likely his nephew. The 1860 Federal census of Wayne County shows two boys, George W, age 16 and Samuel D., age14 living in the W. T. Leeper household. There is no George W. Leeper in the cemetery.
Wm.T.'s five brothers were Greenup, Benjamin,John,Samuel and George W.. My guess is that these two boys were the sons of Greenup Leeper who also moved to Missouri near the time that Wm. T did.
My mother was the youngest daughter of Wm. T. and Margaret Virginia Lee.
