The maternal relationship between Elsie Elma Grubbs and her daughter
Mabel Clare Swick is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DL.
The segmental (via DNA segment triangulation) and total DNA shared between DL and other confirmed descendants of
Ambrose Austen/
Susannah Beard is consistent with the expected ranges for their respective relationships. Since DL descends from Ambrose Austen/Susannah Beard through Elsie Elma Grubbs and her daughter Mabel Clare Swick, the presence of significant shared DNA between DL 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 Elsie Elma Grubbs to Mabel Clare Swick, and ultimately to DL, confirming this direct ancestral connection through multiple generations.
