The maternal relationship between Rebecca Gertrude CASSIDY and her daughter
Mona Veronica MURPHY is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant
Joan Patricia ROBERTS.
The segmental (via DNA segment triangulation) and total DNA shared between Joan Patricia ROBERTS and other confirmed descendants of
Stephen CASSIDY/
Catherine BRITTON is consistent with the expected ranges for their respective relationships. Since Joan Patricia ROBERTS descends from Stephen CASSIDY/Catherine BRITTON through Rebecca Gertrude CASSIDY and her daughter Mona Veronica MURPHY, the presence of significant shared DNA between Joan Patricia ROBERTS and other known descendants of Stephen CASSIDY/Catherine BRITTON validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Stephen CASSIDY/Catherine BRITTON through Rebecca Gertrude CASSIDY to Mona Veronica MURPHY, and ultimately to Joan Patricia ROBERTS, confirming this direct ancestral connection through multiple generations.
