The paternal relationship between John Austen and his daughter
Mary Myrtle Austen 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 John Austen and his daughter Mary Myrtle Austen, the presence of significant shared DNA between MK and other known descendants of Ambrose Austen/Susannah Beard validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Ambrose Austen/Susannah Beard through John Austen to Mary Myrtle Austen, and ultimately to MK, confirming this direct ancestral connection through multiple generations.
