The maternal relationship between Ida May Finch and her son
James Edwin Shinners is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MS.
The segmental (via DNA segment triangulation) and total DNA shared between MS and other confirmed descendants of
John Carpenter/
Elizabeth Jane Higginbottom is consistent with the expected ranges for their respective relationships. Since MS descends from John Carpenter/Elizabeth Jane Higginbottom through Ida May Finch and her son James Edwin Shinners, the presence of significant shared DNA between MS 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 Ida May Finch to James Edwin Shinners, and ultimately to MS, confirming this direct ancestral connection through multiple generations.
