The paternal relationship between Thomas Wendall Cotton and his DNA tested son GFP is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between GFP and other confirmed descendants of
Bernard "barney" R Cain is consistent with the expected ranges for their respective relationships. Since GFP descends from Bernard "barney" R Cain through Thomas Wendall Cotton, the presence of significant shared DNA between GFP and other known descendants of Bernard "barney" R Cain validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA Bernard "barney" R Cain through Thomas Wendall Cotton to GFP, confirming this direct ancestral connection through multiple generations.
