The paternal relationship between Roy Willard 'Budge' Hennesy and his son
Willard 'Dean' Hennesy is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AS.
The segmental (via DNA segment triangulation) and total DNA shared between AS and other confirmed descendants of
James Eaton/
Mary Ann Brocklebank is consistent with the expected ranges for their respective relationships. Since AS descends from James Eaton/Mary Ann Brocklebank through Roy Willard 'Budge' Hennesy and his son Willard 'Dean' Hennesy, the presence of significant shared DNA between AS and other known descendants of James Eaton/Mary Ann Brocklebank validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple James Eaton/Mary Ann Brocklebank through Roy Willard 'Budge' Hennesy to Willard 'Dean' Hennesy, and ultimately to AS, confirming this direct ancestral connection through multiple generations.
