Francis Jester born 1674 is the son of Richard Jester and Frances Church, and is mentioned in his mother's will.

Seems like a VERY likely source for John Merry Jester's ancestor, given he is from Accomack County, Virginia (VA)
Francis siblings = Samuel, Margaret, Thomas, Ann, Susannah, and Richard Jester Jr
Richard Jester was Francis's Father, he
...was born in 1632 in London, England. His parents are unknown.
...married Frances Church in 1660 in Virginia, age 28.
...died in 1690 in Northampton, VA

Frances Church, born circa 1650 and died before 1708/1709
Children:
1. Samuel, born 1672, died Nov 25 1746
2. Richard Jester born circa 1674
3. Thomas Jester circa 1676
4. Susanna 1678
5. Francis 1680
6. Ann 1682
7. Margaret 1684
so John Merry Jester would have to delineate from the males, so that means in his line would be either:
Samuel
Richard
Thomas
or Francis
Given his birth in 1765, that would put his father around 1725-50 born.
His grandfather could be 1685-1735
His great grandfather could be 1645-1720
Great GREAT grandfather born from 1605-1705
1672-1680 is Samuel, Richard, Thomas and Francis so they'd be at LEAST great grandfathers or earlier.
