The maternal relationship between Thelma Bee Coppick and her son
Jerry Wayne Trice is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AF.
The segmental (via DNA segment triangulation) and total DNA shared between AF and other confirmed descendants of
James Chapman/
Ruth Bertha Hammer is consistent with the expected ranges for their respective relationships. Since AF descends from James Chapman/Ruth Bertha Hammer through Thelma Bee Coppick and her son Jerry Wayne Trice, the presence of significant shared DNA between AF and other known descendants of James Chapman/Ruth Bertha Hammer validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple James Chapman/Ruth Bertha Hammer through Thelma Bee Coppick to Jerry Wayne Trice, and ultimately to AF, confirming this direct ancestral connection through multiple generations.
