The maternal relationship between Ida Haffermann and her son Lavern Yeager is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MR.

The segmental (via DNA segment triangulation) and total DNA shared between MR and other confirmed descendants of LH/Friedericke Ludtke is consistent with the expected ranges for their respective relationships. Since MR descends from LH/Friedericke Ludtke through Ida Haffermann and her son Lavern Yeager, the presence of significant shared DNA between MR and other known descendants of LH/Friedericke Ludtke validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple LH/Friedericke Ludtke through Ida Haffermann to Lavern Yeager, and ultimately to MR, confirming this direct ancestral connection through multiple generations.
