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