I think this is a muddled family. Wikitree lists William as the husband of Phoebe Curtis [Courtney-376] and lists them as the parents of a man named John Jones. DAR and SAR applications say that John Jones was born in Virginia in 1744, the son of William Jones and Phoebe possibly Brown. I don’t know if that’s accurate or not, but I’m pretty confident his mother was NOT Phoebe Courtney.
I don’t know the original source of the claim that Phoebe Courtney married William Jones in Virginia and had a son named John. It doesn’t make sense to me that a fifteen or sixteen year old Phoebe, who lived in Maryland, could meet and marry someone in Virginia, have a child, become a widow, and then move again to live with the rest of her family in North Carolina. If Phoebe had a son when her father died, why isn’t he mentioned in the will?
Phoebe Courtney was born in Maryland about 1727 one of several children of Abigail and Robert Courtney.
Abigail died in 1739 and Robert married a woman named Hannah Cook in 1740.
Hannah Cook’s husband had an apprentice, Richard Curtis. When the widowed Hannah married Robert Courtney, Richard’s indenture was transferred to Robert.
The family moved to Onslow County, North Carolina by 1744.
Phoebe married Richard Curtis some time before 1750, since Richard is named as a son-in-law in Robert's will.
Phoebe and Richard moved their family to South Carolina by 1765.
John Jones married a woman named Anna Brown (according to an SAR application in 1768). Anna was supposedly the daughter of Abraham Brown. An Abraham Brown was an abutter of Richard Curtis in Craven County, SC
The Curtises and the Joneses went on to Mississippi where Phoebe died in 1781.
