The maternal relationship between Luella May Swartz and her daughter
Nellie Sophia Miller 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 Luella May Swartz and her daughter Nellie Sophia Miller, 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 Luella May Swartz to Nellie Sophia Miller, and ultimately to SS, confirming this direct ancestral connection through multiple generations.
