The maternal relationship between Lilian Virginia Hartman and her son Ira Bruce Stark is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant VB.

The segmental (via DNA segment triangulation) and total DNA shared between VB and other confirmed descendants of Abraham Hartman is consistent with the expected ranges for their respective relationships. Since VB descends from Abraham Hartman through Lilian Virginia Hartman and her son Ira Bruce Stark, the presence of significant shared DNA between VB and other known descendants of Abraham Hartman validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA Abraham Hartman through Lilian Virginia Hartman to Ira Bruce Stark, and ultimately to VB, confirming this direct ancestral connection through multiple generations.
