You may know this inf., but here is more on your Giles S. Taintor's family.
He is the son of Charles & Sarah (Fox) Taintor and his siblings are: 1.Maria, born Oct. 1802.Married Isaac Briggs of Skeneateles, N.Y., Dec. 1835.
2.Charles, born Dec. 1805.Married Catherine E. Musier of Albany, N.Y. in May of 1830.
3.Sophia, born May 1808.
4.Jesse F.born Aug. 1810.Married Eunice S. Pierce July 1834.
5.Morton, born Sept. 1812.Married Mary Ann Avery of New London (CT?).
6.GILES S. born May 1814 in Buffalo,Erie County, New York.Married Angeline B. Harris, of PHILADELPHIA.My reference is the Charles M. Taintor genealogy book of 1847 & with all his siblings spouses in the CT & NY areas I thought perhaps your reference for VA may be wrong.But, the LDS site has her birth as this:
Angeline B. Harris Pedigree Birth:About 1806Colchester, New London, Connecticut & OLDER than Giles with this reference # Source Information: Film Number:184729.But another source lists her birth as About 1818Of, Natchez, Adams, Mississippi Film Number:1235114, so who knows?I have my family Taintor Bible of 1832 & the LDS site has made errors on my Taintor's dates of birth.
