Rebecca Mae Mason (14/01/1924 - 06/08/1988)

The maternal relationship between Rebecca Mae Mason and her daughter Sandra Lee Irwin is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MM.

The segmental (via DNA segment triangulation) and total DNA shared between MM and other confirmed descendants of John Albertson/Elizabeth Hunter is consistent with the expected ranges for their respective relationships. Since MM descends from John Albertson/Elizabeth Hunter through Rebecca Mae Mason and her daughter Sandra Lee Irwin, the presence of significant shared DNA between MM and other known descendants of John Albertson/Elizabeth Hunter validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John Albertson/Elizabeth Hunter through Rebecca Mae Mason to Sandra Lee Irwin, and ultimately to MM, confirming this direct ancestral connection through multiple generations.
