Hi, I have a question to which someone, hopefully, will be able to provide an explanation. My gggf was named Callahan OConnell. He was named after an uncle. They came to Cambridge Ma in the mid 1800's from Mallow, Cork area via Portland, Maine. They are buried in Arlington, Ma nearby. I recently located another person of the same name buried in Holyoke, Ma who came from Ireland in 1898. Both of these men have family members named Daniel, Jeremiah and William H. on the census records for these towns. It would appear that they are related due to the similarities of the family names but particularly the name Callahan OConnell which seems to be quite unique. Am I correct or is Callahan used as a first name in Ireland, like Kelly or Ryan are? Take care, Ed Callahan
