1/2 Chickasaw
At least for the present time, I am accepting Family Ties' [http://awt.ancestry.com/cgi-bin/igm.cgi?op=GET&db=familyties&id=I06405] identification of the mysterious "Mrs. Frazier" as Sally McCoy. This does not seem to be a universal opinion. I reproduce here the justifications given:
"Sally is listed on the 1818 Chickasaw Annuity Roll living within the household of Major James Colbert. She is using the surname McCoy. In the William C. Thompson et. al. vs. Choctaw Nation case he identifies Dickson Frazier as his uncle (pg. 15 of 1818 roll). This would mean that Harry Frazier could have been her second husband. If she is the same person known as Mrs. Frazier, who married James Colbert, the marriage was prior to 1799, which brings into question why she would be using the name McCoy in 1818. This can be explained in that her maiden name was McCoy and her husband a full blood Choctaw, thus her first three children would have taken her English surname, with her husbands name was being a Choctaw name only (Itobiah according to research papers of the late Cecil Lee Pinkston-Vinson). Additionally to support the assumption she was the wife of Major James Colbert was affidavit in the 'William C. Thompson et al vs. the Choctaw Nation', that states that Margaret had another sister that died young in Mississippi. Kerry Armstrong states that Mrs. Frazier was a half blood Chickasaw. This is in line with Thompson family tradition that states her husband was a half blood or even full blood Choctaw and thereby making her children Margaret, William and James McCoy, 1/4 Chickasaw and 1/4 to 1/2 Choctaw. Therefore, my assumption of which I hope to prove beyond a doubt, is that she is the daughter of Joshua McCoy Jr. and a Chickasaw wife. That she first married or lived with a full blood or half blood Choctaw man and then married Harry Fraser, followed by a marriage to Major James Colbert, which, although it ended she remained close to, enough to still be in his household in 1818 along with another of his ex-wives, Mrs. McIntosh, as listed on the annuity roll.
