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