The maternal relationship between Geraldine Bost and her son KWC is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MBC.
The segmental (via DNA segment triangulation) and total DNA shared between MBC and other confirmed descendants of
Jacob Carner/
Sarah Ellen Albertson is consistent with the expected ranges for their respective relationships. Since MBC descends from Jacob Carner/Sarah Ellen Albertson through Geraldine Bost and her son KWC, the presence of significant shared DNA between MBC and other known descendants of Jacob Carner/Sarah Ellen Albertson validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Jacob Carner/Sarah Ellen Albertson through Geraldine Bost to KWC, and ultimately to MBC, confirming this direct ancestral connection through multiple generations.
