The maternal relationship between Ida May Critchlow and her daughter
Ida Mae Barlow is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DB.
The segmental (via DNA segment triangulation) and total DNA shared between DB and other confirmed descendants of
Johannes Kürner/
Christiana Heffilfinger is consistent with the expected ranges for their respective relationships. Since DB descends from Johannes Kürner/Christiana Heffilfinger through Ida May Critchlow and her daughter Ida Mae Barlow, the presence of significant shared DNA between DB 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 Ida May Critchlow to Ida Mae Barlow, and ultimately to DB, confirming this direct ancestral connection through multiple generations.
