The paternal relationship between James Andrew Denean and his daughter
Josephine Mary Denean is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LAD.
The segmental (via DNA segment triangulation) and total DNA shared between LAD and other confirmed descendants of
John Denean/
Elizabeth Jean Alleman is consistent with the expected ranges for their respective relationships. Since LAD descends from John Denean/Elizabeth Jean Alleman through James Andrew Denean and his daughter Josephine Mary Denean, the presence of significant shared DNA between LAD and other known descendants of John Denean/Elizabeth Jean Alleman validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple John Denean/Elizabeth Jean Alleman through James Andrew Denean to Josephine Mary Denean, and ultimately to LAD, confirming this direct ancestral connection through multiple generations.
