The maternal relationship between Rosilla Haven and her daughter
Mabel Marguerite Sackett is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GG.
The segmental (via DNA segment triangulation) and total DNA shared between GG and other confirmed descendants of
Ephraim Mallory/
Desire Oates is consistent with the expected ranges for their respective relationships. Since GG descends from Ephraim Mallory/Desire Oates through Rosilla Haven and her daughter Mabel Marguerite Sackett, the presence of significant shared DNA between GG and other known descendants of Ephraim Mallory/Desire Oates validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Ephraim Mallory/Desire Oates through Rosilla Haven to Mabel Marguerite Sackett, and ultimately to GG, confirming this direct ancestral connection through multiple generations.
