The paternal relationship between Leonard Arnold and his son DWA is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JA.

The segmental (via DNA segment triangulation) and total DNA shared between JA and other confirmed descendants of George William Arnold/Louisa FOX is consistent with the expected ranges for their respective relationships. Since JA descends from George William Arnold/Louisa FOX through Leonard Arnold and his son DWA, the presence of significant shared DNA between JA and other known descendants of George William Arnold/Louisa FOX validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple George William Arnold/Louisa FOX through Leonard Arnold to DWA, and ultimately to JA, confirming this direct ancestral connection through multiple generations.
