I know Dunn's from Utica, NY. John Joseph Dunn ran a bar in Utica. His mother died when he was ten. His father put him and siblings in an orphan's home in Utica. His mother's name was Julia Delaney, His father, Michael Dunne....it changed to Dunn either in his father or grand-father's lifetime. John had a sister Anna and we think he had a brother Thomas. There were other siblings as well. John J. Dunn died December 25, 1977 in Utica, New York. He was married to Grace Hoban. He had four children, John Jr. William, Eileen and Dorothy, all deceased. Is any of this useful to you? Please let me know. Thanks Jamie
