The maternal relationship between Ceciley Porte and her daughter
Debra Suderman is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EG.
The segmental (via DNA segment triangulation) and total DNA shared between EG and other confirmed descendants of
Andreas Ludwig Grünke/
Mathilde Hübner is consistent with the expected ranges for their respective relationships. Since EG descends from Andreas Ludwig Grünke/Mathilde Hübner through Ceciley Porte and her daughter Debra Suderman, the presence of significant shared DNA between EG and other known descendants of Andreas Ludwig Grünke/Mathilde Hübner validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Andreas Ludwig Grünke/Mathilde Hübner through Ceciley Porte to Debra Suderman, and ultimately to EG, confirming this direct ancestral connection through multiple generations.
