The maternal relationship between Cordelia Decamp and her daughter
Hazel Mabel Masteller is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JC.
The segmental (via DNA segment triangulation) and total DNA shared between JC and other confirmed descendants of
Gideon Decamp/
Elizabeth Dougal is consistent with the expected ranges for their respective relationships. Since JC descends from Gideon Decamp/Elizabeth Dougal through Cordelia Decamp and her daughter Hazel Mabel Masteller, the presence of significant shared DNA between JC and other known descendants of Gideon Decamp/Elizabeth Dougal validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Gideon Decamp/Elizabeth Dougal through Cordelia Decamp to Hazel Mabel Masteller, and ultimately to JC, confirming this direct ancestral connection through multiple generations.
