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