TRIANGULATION was the method used in proving descent from Rev. War Soldier Reuben Bates (1731-1800).
Exact match was made between two DNA donors, who by paper work,were descendants of sons of Rev. War Soldier Reuben Bates.Sons of Reuben Bates were, by paper work:
1. Donor descendant of James Bates (1762-1825) 2. Donor descendant of Reuben Bates, Junior (1771-1853) --------------------------------------
Triangulation - /tri·an·gu·la·tion/ - A method of determining the Ancestral Haplotype from the haplotype data of known direct line descendants. In Genetic Genealogy, the process of determining the Y chromosome DNA Ancestral Haplotype of a male ancestor by looking at the allele values of the DYS markers in the haplotypes of the tested individuals in a surname project who descend from that ancestor by focusing specifically on the direct paternal line descendants of two or more known and different sons of the common male ancestor. Unless there is an exact match at all alleles at all DYS markers in the haplotypes of the two different direct male lines of descendants, at least three haplotypes are required to triangulate and deduce the ancestral allele for each marker. A typical descendant chart looks like a triangle with the ancestor at the apex. See this page for an example of a Descendant and DNA Inheritance Chart.
