It appears to have been Thomas Harrison Sr. (rather than Jr.) who owned the land adjoining Charles Blancherd before 1714. Thomas Harrison Sr. filed his will in 1720 in Prince George. He had a brother named Benjamin Harrison.
"HARRISON. The Harrison family, of which there are several members in Callaway Co., is one of the most distinguished in America. It sprang from some of the best blood of England, and has given to that country and America, several of their most celebrated characters. John, Benjanin and Thomas Harrison were sons of a family of English nobility, and were born in the town of Feuby, Yorkshire.
Benjamin Harrison was born in 1694. He had 2 sons, Benjamin and Robert. The former was the father of Hon. Benjamin Harrison, one of the signers of the Declaration of Independence, and who was the father of General William Henry Harrison, President of the United States.
Thomas, the younger brother of John and Benjamin Harrison, was born in 1695.
He married HANNAH MORRISON, of England, by whom he had 6 sons... John, Benjamin,
Thomas, Jr., Samuel, Daniel, and James, all of whom came to America after the
death of their parents, and settled in the state of Maryland."
1702 Charles City County VA
"William Byrd, while residing on the north bank of the James, had inherited
large holdings on the south side and, also, beginning in 1702, commanded the
entire militia of the old Henrico and Charles City shires. Richard Bland and
Joshua Wynne (or Winn) were the burgesses for the entire Charles City. Other
officers, most of whom were living on the south side of the James, were Charles
Goodrich, sheriff; William Randolph, escheator;
Benjamin Harrison, clerk; and John Bolling, surveyor."
1705 Prince George County VA - Thomas Harrison
"Because courts had been held previously at Merchant's Hope, it is assumed
that they continued there when Prince George began functioning as a separate
county. At any rate, a court 'was holden' on 14 April 1708 at that place. The
justices named three of their members as eligible for the office of sheriff,
which was being filled in 1705 by William Eppes, as shown on a bail bond given
by John Owen and Thomas Harrison on April 7. The three eligible were Major Joshua
Wynne, William Eppes, Jr., and Captain John Hamlin. The clerk was Richard Bland."
The Prince George Will & Deeds Book includes a 1720 deed that specifically places the same Thomas Harrison Jr. on Powell's Creek whose headwaters were near the Blackwater River. Powell's Creek was precisely where Charles Sparrow and Richard Tye owned land and John Blackard was listed on their 1650 patent for the headrights grant to that property. This means that around 1650 John Blackard also lived in this area.
