Irene Ida Henderson (25/12/1909 - 27/01/1980)

The maternal relationship between Irene Ida Henderson and her son John Walter Lamme is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JL.

The segmental (via DNA segment triangulation) and total DNA shared between JL and other confirmed descendants of Albert Carner/Mary Jane Stonecipher is consistent with the expected ranges for their respective relationships. Since JL descends from Albert Carner/Mary Jane Stonecipher through Irene Ida Henderson and her son John Walter Lamme, the presence of significant shared DNA between JL and other known descendants of Albert Carner/Mary Jane Stonecipher validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Albert Carner/Mary Jane Stonecipher through Irene Ida Henderson to John Walter Lamme, and ultimately to JL, confirming this direct ancestral connection through multiple generations.
