The maternal relationship between Ida Belle "Minnie" Glasford and her son
Frank Xavier Claveau is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RDM.
The segmental (via DNA segment triangulation) and total DNA shared between RDM and other confirmed descendants of
Isaac M. Glasford/
Diantha Matilda Devore is consistent with the expected ranges for their respective relationships. Since RDM descends from Isaac M. Glasford/Diantha Matilda Devore through Ida Belle "Minnie" Glasford and her son Frank Xavier Claveau, the presence of significant shared DNA between RDM and other known descendants of Isaac M. Glasford/Diantha Matilda Devore validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Isaac M. Glasford/Diantha Matilda Devore through Ida Belle "Minnie" Glasford to Frank Xavier Claveau, and ultimately to RDM, confirming this direct ancestral connection through multiple generations.
