Grace D Shintaffer (Mar 1891 - 1945)

The maternal relationship between Grace D Shintaffer and her daughter Anna Katherine Calvin is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant REK.

The segmental (via DNA segment triangulation) and total DNA shared between REK and other confirmed descendants of Henry Meeker/Sarah Lindsley is consistent with the expected ranges for their respective relationships. Since REK descends from Henry Meeker/Sarah Lindsley through Grace D Shintaffer and her daughter Anna Katherine Calvin, the presence of significant shared DNA between REK and other known descendants of Henry Meeker/Sarah Lindsley validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Henry Meeker/Sarah Lindsley through Grace D Shintaffer to Anna Katherine Calvin, and ultimately to REK, confirming this direct ancestral connection through multiple generations.
