The paternal relationship between Raymond Krumbach and his daughter PK is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KPK.
The segmental (via DNA segment triangulation) and total DNA shared between KPK and other confirmed descendants of
Wilhelm Carl Hackbarth/
Anna Dorothea Hafemann is consistent with the expected ranges for their respective relationships. Since KPK descends from Wilhelm Carl Hackbarth/Anna Dorothea Hafemann through Raymond Krumbach and his daughter PK, the presence of significant shared DNA between KPK and other known descendants of Wilhelm Carl Hackbarth/Anna Dorothea Hafemann validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Wilhelm Carl Hackbarth/Anna Dorothea Hafemann through Raymond Krumbach to PK, and ultimately to KPK, confirming this direct ancestral connection through multiple generations.
