This profile has been added to the Jewish Choctaw project on Geni. I have not seen any persuasive evidence that there were Jewish Choctaws and the Overview (About) of this individual does not provide such evidence.
(1) mtDNA mutates very slowly so if the claim is that the mtDNA is the evidence for being Jewish, that is impossible. If the large haplogroup, such as J or J1 or J2 is from the Near East, it is from very ancient times, well before there was a Jewish religion or Jewish people. And millions of people who are of European descent share these haplogroups because in ancient times Near Eastern people settled in Europe.
From Wikipedia. https://en.wikipedia.org/wiki/Haplogroup_J_(mtDNA)
Within Europe, >2% frequency distribution of mtDNA J is as follows:[11]
J* = Ireland — 12%, England-Wales — 11%, Scotland — 9%, Orkney — 8%, Germany — 7%, Russia (European) — 7%, Iceland — 7%, Austria-Switzerland — 5%, Finland-Estonia — 5%, Spain-Portugal — 4%, France-Italy — 3%
J1a = Austria-Switzerland — 3%
J1b1 = Scotland — 4%
J2 = France-Italy — 2%
J2a = Homogenously spread in Europe; absent in the nations around the Caucasus; not known to be found elsewhere.[2]
J2b1 = Virtually absent in Europe; found in diverse forms in the Near East.[2]
J2b1a = Found in Western Europe and Russia.[2]
