The maternal relationship between Mildred Broughton and her son RNW is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AW.
The segmental (via DNA segment triangulation) and total DNA shared between AW and other confirmed descendants of
Joseph Kinloch is consistent with the expected ranges for their respective relationships. Since AW descends from Joseph Kinloch through Mildred Broughton and her son RNW, the presence of significant shared DNA between AW and other known descendants of Joseph Kinloch validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Joseph Kinloch through Mildred Broughton to RNW, and ultimately to AW, confirming this direct ancestral connection through multiple generations.
