The maternal relationship between Geraldine DeVinna and her DNA tested son DS is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between DS and other confirmed descendants of
Abram Tompkins/
Mary Ann Eaton is consistent with the expected ranges for their respective relationships. Since DS descends from Abram Tompkins/Mary Ann Eaton through Geraldine DeVinna, the presence of significant shared DNA between DS and other known descendants of Abram Tompkins/Mary Ann Eaton validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Abram Tompkins/Mary Ann Eaton through Geraldine DeVinna to DS, confirming this direct ancestral connection through multiple generations.
