The maternal relationship between Florence Lydia Carpenter and her son Marvin Martin Werner is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KN.

The segmental (via DNA segment triangulation) and total DNA shared between KN and other confirmed descendants of John Carpenter/Elizabeth Jane Higginbottom is consistent with the expected ranges for their respective relationships. Since KN descends from John Carpenter/Elizabeth Jane Higginbottom through Florence Lydia Carpenter and her son Marvin Martin Werner, the presence of significant shared DNA between KN and other known descendants of John Carpenter/Elizabeth Jane Higginbottom validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John Carpenter/Elizabeth Jane Higginbottom through Florence Lydia Carpenter to Marvin Martin Werner, and ultimately to KN, confirming this direct ancestral connection through multiple generations.
