There's probably another John Mears around somewhere for him to be the son of. There were lots of Mears.

We still have the incompatibility in birth dates (c. 1705 vs. 1710), and the unexplained George Mears back in Accomack County, and said George Mears administering the Accomack County estate of Mark Mears.

I found Jonathan Mears - he's a nephew of Mark's: http://espl-genealogy.org/MilesFiles/site/p542.htm#i54140 - but Andrew Mears is as unaccounted-for as George.

We also have to consider Mark Mears being left 100 acres of Accomack County land in his father's will of 1745 (probated 29 September 1747), plus assorted personal items. So why would he upstakes and go to North Carolina? (The Accomack County land was *certainly not* sold during Mark's lifetime - George Mears inherited it and passed it on to his son John, who (finally) sold it to Francis Savage.)

Accomack County families are very popular with researchers of similarly-named families with weak or no family trees - they get latched onto willy-nilly, and then everybody *thinks* they know where they came from.

There were Mears families in New England and i Maryland whose connection, if any, to the Accomack County Mearses is totally obscure.
