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