The paternal relationship between Irvel Neil Morford and his son JM is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JM.

The segmental (via DNA segment triangulation) and total DNA shared between JM and other confirmed descendants of Lathrop Meeker/Sophronia Maria Tompkins is consistent with the expected ranges for their respective relationships. Since JM descends from Lathrop Meeker/Sophronia Maria Tompkins through Irvel Neil Morford and his son JM, the presence of significant shared DNA between JM and other known descendants of Lathrop Meeker/Sophronia Maria Tompkins validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Lathrop Meeker/Sophronia Maria Tompkins through Irvel Neil Morford to JM, and ultimately to JM, confirming this direct ancestral connection through multiple generations.
