Philip Waterworth has spent over ten years researching and accumulating a vast amount of data and documentation to create the Descendants of James Ahern Sarah Casey and Mary Boland. This information is now in a document that can be shared with anyone who may use it as a basis to continue their own research. Research is still ongoing, and the ever-ending story of those who decide to publish some of the material starts with his Great Grandfather James (Jim Man) Ahern and his 21 children.
