The maternal relationship between Isabella Emerson and her daughter
Emma Isabelle Wickens 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 Isabella Emerson and her daughter Emma Isabelle Wickens, the presence of significant shared DNA between NAS and other known descendants of William Emerson validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA William Emerson through Isabella Emerson to Emma Isabelle Wickens, and ultimately to NAS, confirming this direct ancestral connection through multiple generations.
