The maternal relationship between Nellie Sophia Miller and her son
John Edward Jack Holmes is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SS.
The segmental (via DNA segment triangulation) and total DNA shared between SS and other confirmed descendants of
Johannes Kürner/
Christiana Heffilfinger is consistent with the expected ranges for their respective relationships. Since SS descends from Johannes Kürner/Christiana Heffilfinger through Nellie Sophia Miller and her son John Edward Jack Holmes, the presence of significant shared DNA between SS and other known descendants of Johannes Kürner/Christiana Heffilfinger validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johannes Kürner/Christiana Heffilfinger through Nellie Sophia Miller to John Edward Jack Holmes, and ultimately to SS, confirming this direct ancestral connection through multiple generations.
