The maternal relationship between Irene Hinz and her daughter
Laurel Eastburn is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SE.
The segmental (via DNA segment triangulation) and total DNA shared between SE and other confirmed descendants of LH/
Friedericke Ludtke is consistent with the expected ranges for their respective relationships. Since SE descends from LH/Friedericke Ludtke through Irene Hinz and her daughter Laurel Eastburn, the presence of significant shared DNA between SE 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 Irene Hinz to Laurel Eastburn, and ultimately to SE, confirming this direct ancestral connection through multiple generations.
