I have a Mary Giles on my maternal line for years now. But I copied it from Ancestry.com. There is no sources listed anywhere. She married Isaac Falconbury (Falkenburg, Falconborough, etc), supposedly about 1756. Her first (and only?) child was Jacob Falconbury, born 1757 in Anson County, North Carolina. There was a John Giles who bought or sold some land there, so I tentatively list him as her father.
