I found the will of Mary A. Eatherton (1786-died between 1862 &1863) at the Virginia Library under Chancery Reports. She list her siblings as: Sarah W. Seay Sowder(1798-?), Carr W. Seay(1791-1860), Diana Seay Chiles( about !800-?) and Nancy Seay Moran (?-?).
According to research she was from Hanover County Virginia. Married Benjamin Eatherton and lived in Spotsylvania County Virginia. After Benjamin's death moved back to Hanover County near her sister Sarah W. Seay Sowder. Does any one know who could be their parents? I am ruling out James and Sarah Spicer because Mary was born in 1786.
