The maternal relationship between Mary Myrtle Austen and her daughter
Rosella Wertz is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MK.
The segmental (via DNA segment triangulation) and total DNA shared between MK and other confirmed descendants of
Ambrose Austen/
Susannah Beard is consistent with the expected ranges for their respective relationships. Since MK descends from Ambrose Austen/Susannah Beard through Mary Myrtle Austen and her daughter Rosella Wertz, the presence of significant shared DNA between MK and other known descendants of Ambrose Austen/Susannah Beard validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Ambrose Austen/Susannah Beard through Mary Myrtle Austen to Rosella Wertz, and ultimately to MK, confirming this direct ancestral connection through multiple generations.
