I have Creans from Holyoke in my tree as well. They were from Deelis near Castlegregory on the Dingle peninsula.
My great grandmother Honoria Crean married Fred Beaudry and they settled in Holyoke. Another sister Catherine married Edward Scanlon and another Mary Crean married Jeremiah Moynihan in Holyoke. A brother John Crean lived in suburban NY, married to Nellie Moriarty. All of these events occurred in the 1900-1920 timeframe. There are a few siblings whose fate I cannot determine. Parents were Michael Crean and Nora Rohan.
