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