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