It is doubtful that Percival and his extended family, including Henry and Sarah Holland, all moved to Georgia at the same time. Son David Clay seems to have the earliest land record with a survey in Washington County, GA on the 5th of December, 1785. The formal grant deed for that land is dated August 2, 1786.
Percival, Sr. receives a warrant for land dated December 2, 1788 in Wilkes County, GA. This land was near the “Shoals on the Ogeechee” river, which would become an important reference point for sorting out who was involved with Percival and his family.
The best view of the available evidence is that on September 22, 1789, David Clay married Eve Hardin in a ceremony held at the Shoals. Eve (Hardin) Clay appears to have misremembered the date when she filled out her pension application decades later, claiming it was 1792. However, the declaration of Henry Holland stated that his oldest child was “a sucking infant” when the marriage was celebrated, and that only fits with a 1789 date.
The ceremony was conducted by John Hatcher, a Justice of the Peace, according to Henry Holland’s declaration. That also argues for an earlier date. When Warren County, GA was formed in December of 1793, John Hatcher was a Captain of the militia district that included the Wilkes side of the Shoals, when it was reassigned from Wilkes County to Warren County.
How this marriage came to be arranged is informed by the fact that Eve Hardin’s brother Adam Hardin owned property in this same area of Wilkes County (which would become Warren County). I would bet that Adam Hardin and Percival, Sr. had a conversation along the lines of “my sister needs a husband” and “my son needs a wife.” By 1789, David Clay was roughly 30 years old and well-established in Washington County, GA (from 1785), which was on the other side of the Shoals from where all these others lived.
An arranged marriage makes the most sense because Eve had a reputation as a witch-type woman who had a very sharp tongue. After David won a plantation in Wilkinson County in the 1805 land lottery, he would frequently escape to there to get away from Eve, according to family legend.
In any case, Percival, Sr. appears to have lived out his life in Warren County. The only later record we have of him is that his widow Sarah Clay sold his land sometime before June 10, 1803, when the buyer sold the land on to somebody else. The date when Sarah sold the land is not given. It should be presumed that after selling the land, Sarah would have moved to live with one of her children, and there would not be any further record of her, either.
