The next child of Thomas Whitlock (abt. 1745 – 1830) and wife Hannah Phillips, their third child if I have their children in correct order, was a son Charles Whitlock. A number of previous postings contain biographical information about Charles. As I state in a previous posting, in my view, Thomas and his siblings were likely raised by their older brother Charles after the Whitlock parents, James Whitlock and Agnes Christmas, died, James in 1749 in Louisa County, Virginia, and Agnes between 1750 and 1757, probably also in Louisa.
I don’t have documentary proof of my deduction that, as the oldest of James and Agnes’s children, Thomas’s brother Charles brought his younger siblings to Albemarle County, where he lived from 1760 or a bit earlier up to around 1780, when he moved to Surry County, North Carolina. But such information as I have suggests to me that this is what happened. As the posting linked above states, in my view Thomas Whitlock named his only son Charles after the older brother who raised him.
