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
Joseph Stonecypher/
Julia Ann Watson is consistent with the expected ranges for their respective relationships. Since MBC descends from Joseph Stonecypher/Julia Ann Watson through Geraldine Bost and her son KWC, the presence of significant shared DNA between MBC and other known descendants of Joseph Stonecypher/Julia Ann Watson validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Joseph Stonecypher/Julia Ann Watson through Geraldine Bost to KWC, and ultimately to MBC, confirming this direct ancestral connection through multiple generations.
