The maternal relationship between Naomi Humphrey and her daughter
Ella May Cecil is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PP.
The segmental (via DNA segment triangulation) and total DNA shared between PP and other confirmed descendants of AH/NR is consistent with the expected ranges for their respective relationships. Since PP descends from AH/NR through Naomi Humphrey and her daughter Ella May Cecil, the presence of significant shared DNA between PP and other known descendants of AH/NR validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple AH/NR through Naomi Humphrey to Ella May Cecil, and ultimately to PP, confirming this direct ancestral connection through multiple generations.
