Hello Brian, hope you are well. I am not sure if this helps and/or you may already be aware - my grandmother Mary Katherine Hatton (married name was Rooney) was the sister of Hannah Theresa Hatton. I was recently talking about that part of my family to my mum (the daughter of Mary Rooney (nee Hatton). My mum certainly has a lot insight into re her mothers family and in fact told me only recently about how little Hannah died. In fact you may already know my mother but if not and there anything I can do to help you? Do let me know. Kind regards, Colette
