The paternal relationship between Ernest Prill and his son GP is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GP2.

The segmental (via DNA segment triangulation) and total DNA shared between GP2 and other confirmed descendants of JR/Wilhelmine Ernestine Grade is consistent with the expected ranges for their respective relationships. Since GP2 descends from JR/Wilhelmine Ernestine Grade through Ernest Prill and his son GP, the presence of significant shared DNA between GP2 and other known descendants of JR/Wilhelmine Ernestine Grade validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple JR/Wilhelmine Ernestine Grade through Ernest Prill to GP, and ultimately to GP2, confirming this direct ancestral connection through multiple generations.
