Honestly I have noted Eastins with origins from both Philip or Thomas who may or may not have been siblings from/of VA in Illinois,MO,KY,AL,GA,LA ,off the top of my head I cant say what the map looked like at that time but given TN was basically surrounded by those locations it wouldnt seem unreasonable that some were there.Tell me more about the Whitlock neighborhood.I have seen trees that have a lot more children of both said philip and Thomas attached to them but they arent seen in later census,perhaps they would show up in tax lists Im not sure.I honestly have no idea nor have seen a citation how Sarah Whitlock fits in,if there were a will that tied her to the family Ive never heard tell of it.
Two VA wills below the one for John Douglas is assumed to mention the wife of Philip mentioned in the next will.Perhaps you will get something from these.

"quoting a message board post below"
The Eastin orphans (John, Charles, Reuben, Nancy and Mary) had to be all 14 years old or older by 27 February, 1783, as they were allowed to choose their own guardian, instead of just being assigned one. Charles and Reuben would have been over 16 years old by the time of the 1784 Personal Property Tax lists (taken in mid-1783) as they appear on that list: John would have turned 21 in (late) 1783, as he appears as a separate tithable in the 1784 tax list. Reuben was over 16, but still under 21 in 1784 (1785 tax list). Probably, he was still underage in 1787 (1788 list). Charles probably came of age in 1785-86 (hard to tell exactly due to the incompleteness of the 1786 tax list). The daughters, who were not mentioned in tax lists (nor were they heads of households) are more difficult to approximate birth dates for, and I do not really have enough evidence to try to indicate birth dates for them."
I can tell you children I believe to be sons of Thomas Eastin of Albermarle children born between 1740ish -?maybe 1760ish William,Achilles,Augustine,Stephen,John,Philip.Im sure there were others and probably some females.You can start looking at them.
You are probably looking for a female line married in prior 1781.
