The paternal relationship between Dennis Dwight "dock" Hatcher and his son
Dwight Joel Hatcher is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EHW.
The segmental (via DNA segment triangulation) and total DNA shared between EHW and other confirmed descendants of
James Fulton Hatcher/
Catherine Elizabeth Martin is consistent with the expected ranges for their respective relationships. Since EHW descends from James Fulton Hatcher/Catherine Elizabeth Martin through Dennis Dwight "dock" Hatcher and his son Dwight Joel Hatcher, the presence of significant shared DNA between EHW 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 Dennis Dwight "dock" Hatcher to Dwight Joel Hatcher, and ultimately to EHW, confirming this direct ancestral connection through multiple generations.
