The paternal relationship between John Clifford Mann and his daughter
Roberta Carolyn Mann is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EC.
The segmental (via DNA segment triangulation) and total DNA shared between EC and other confirmed descendants of
William Ballard/
Elizabeth Steppe is consistent with the expected ranges for their respective relationships. Since EC descends from William Ballard/Elizabeth Steppe through John Clifford Mann and his daughter Roberta Carolyn Mann, the presence of significant shared DNA between EC and other known descendants of William Ballard/Elizabeth Steppe validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple William Ballard/Elizabeth Steppe through John Clifford Mann to Roberta Carolyn Mann, and ultimately to EC, confirming this direct ancestral connection through multiple generations.
