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