I hope you will appreciate what I'm about to tell you. We have tested 15 different families in the Southeast US from Alabama , the Carolinas, Virginia, West Virginia Tennessee, Kentucky. This was autosomal DNA. We tested rural families ( to avoid the possible affects of inward migration)who have been in their places since the Civil War. Every individual was related to Jewish populations and matched DNA from Israel. All matched Iberia, Berber, Arab and all matched Cherokee, Miwok, Athabaskin Indian. Interestingly, none had British or Western Europe to any substantial amount. We don't understand this. I'm amusing we are descendants of Sephardim who came here without being noticed. Many of us are returning/converting. My family has all converted and we love being Jews. There are apparently millions of us in the Americas. And we American men are circumcised so we have the mark of the covenant.
