The maternal relationship between Helen Louise Dunlap and her DNA tested daughter ST is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between ST and other confirmed descendants of HB/
Malinda Tolbert is consistent with the expected ranges for their respective relationships. Since ST descends from HB/Malinda Tolbert through Helen Louise Dunlap, the presence of significant shared DNA between ST and other known descendants of HB/Malinda Tolbert validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple HB/Malinda Tolbert through Helen Louise Dunlap to ST, confirming this direct ancestral connection through multiple generations.
