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