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