I just found this 10 year old thread. I do not have much on your Grandfather directly but it appears that his siter married my Great Grandfather. Bridget Nihill married James T Malarney. Mary, Katie, Josephine, MargUrite, Genevieve, Lauretta, Agnes and Cyrilla were all sisters of Thomas Patrick Nihilll. Their parents were Thomas and Cathrine (O'Donnell). What do you know about the accidents that took their parents?
