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