The maternal relationship between Helen June Cessna and her DNA tested son RC is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between RC and other confirmed descendants of
Jonathan Cessna/
Rebecca Worley is consistent with the expected ranges for their respective relationships. Since RC descends from Jonathan Cessna/Rebecca Worley through Helen June Cessna, the presence of significant shared DNA between RC and other known descendants of Jonathan Cessna/Rebecca Worley validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Jonathan Cessna/Rebecca Worley through Helen June Cessna to RC, confirming this direct ancestral connection through multiple generations.
