The paternal relationship between Hubert Jr "Herb" Ferkel and his DNA tested daughter GAF is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between GAF and other confirmed descendants of
Hubert Jacob Ferkel/
Thelma Mae Wardell is consistent with the expected ranges for their respective relationships. Since GAF descends from Hubert Jacob Ferkel/Thelma Mae Wardell through Hubert Jr "Herb" Ferkel, the presence of significant shared DNA between GAF and other known descendants of Hubert Jacob Ferkel/Thelma Mae Wardell validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Hubert Jacob Ferkel/Thelma Mae Wardell through Hubert Jr "Herb" Ferkel to GAF, confirming this direct ancestral connection through multiple generations.
