The maternal relationship between Sarah Belle Fowler and her daughter
Frances Vivian Upton is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SRB.
The segmental (via DNA segment triangulation) and total DNA shared between SRB and other confirmed descendants of
David Asbury Fowler/
Mariah Anne York is consistent with the expected ranges for their respective relationships. Since SRB descends from David Asbury Fowler/Mariah Anne York through Sarah Belle Fowler and her daughter Frances Vivian Upton, the presence of significant shared DNA between SRB and other known descendants of David Asbury Fowler/Mariah Anne York validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple David Asbury Fowler/Mariah Anne York through Sarah Belle Fowler to Frances Vivian Upton, and ultimately to SRB, confirming this direct ancestral connection through multiple generations.
