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