The paternal relationship between Gustav Adolph Timnick and his son
Andrei Timnick is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SR.
The segmental (via DNA segment triangulation) and total DNA shared between SR and other confirmed descendants of
Johann Radke/
Anna Gartzke is consistent with the expected ranges for their respective relationships. Since SR descends from Johann Radke/Anna Gartzke through Gustav Adolph Timnick and his son Andrei Timnick, the presence of significant shared DNA between SR and other known descendants of Johann Radke/Anna Gartzke validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Radke/Anna Gartzke through Gustav Adolph Timnick to Andrei Timnick, and ultimately to SR, confirming this direct ancestral connection through multiple generations.
