The maternal relationship between Sarah Elizabeth Barnard and her daughter
Minerva Josephine Powell is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RGW.
The segmental (via DNA segment triangulation) and total DNA shared between RGW and other confirmed descendants of
James Alexander Short/
Elizabeth Moore is consistent with the expected ranges for their respective relationships. Since RGW descends from James Alexander Short/Elizabeth Moore through Sarah Elizabeth Barnard and her daughter Minerva Josephine Powell, the presence of significant shared DNA between RGW and other known descendants of James Alexander Short/Elizabeth Moore validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple James Alexander Short/Elizabeth Moore through Sarah Elizabeth Barnard to Minerva Josephine Powell, and ultimately to RGW, confirming this direct ancestral connection through multiple generations.
