The paternal relationship between William Earl Smith and his son JS is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SP.
The segmental (via DNA segment triangulation) and total DNA shared between SP and other confirmed descendants of
Charles Perry Upton/
Celinda Ellen Gray is consistent with the expected ranges for their respective relationships. Since SP descends from Charles Perry Upton/Celinda Ellen Gray through William Earl Smith and his son JS, the presence of significant shared DNA between SP and other known descendants of Charles Perry Upton/Celinda Ellen Gray validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Charles Perry Upton/Celinda Ellen Gray through William Earl Smith to JS, and ultimately to SP, confirming this direct ancestral connection through multiple generations.
