The paternal relationship between Gary Clifford Powell and his DNA tested daughter SF is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between SF and other confirmed descendants of
James Fulton Hatcher/
Catherine Elizabeth Martin is consistent with the expected ranges for their respective relationships. Since SF descends from James Fulton Hatcher/Catherine Elizabeth Martin through Gary Clifford Powell, the presence of significant shared DNA between SF and other known descendants of James Fulton Hatcher/Catherine Elizabeth Martin validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple James Fulton Hatcher/Catherine Elizabeth Martin through Gary Clifford Powell to SF, confirming this direct ancestral connection through multiple generations.
