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