The maternal relationship between D van Arragon and her daughter
B van Til is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EO2.
The segmental (via DNA segment triangulation) and total DNA shared between EO2 and other confirmed descendants of GVA is consistent with the expected ranges for their respective relationships. Since EO2 descends from GVA through D van Arragon and her daughter B van Til, the presence of significant shared DNA between EO2 and other known descendants of GVA validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA GVA through D van Arragon to B van Til, and ultimately to EO2, confirming this direct ancestral connection through multiple generations.
