The paternal relationship between Ira Bruce Stark and his DNA tested daughter VS is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between VS and other confirmed descendants of
Abraham Hartman is consistent with the expected ranges for their respective relationships. Since VS descends from Abraham Hartman through Ira Bruce Stark, the presence of significant shared DNA between VS and other known descendants of Abraham Hartman validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA Abraham Hartman through Ira Bruce Stark to VS, confirming this direct ancestral connection through multiple generations.
