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