Hi. Okay, Dalton, Massachusetts is just East of Pittsfield, Massachusetts. I was Born & Raised in Pittsfield, MA & lived there until 1980 when I moved to California. I am Irish as well and Ancestrally related to the Murphy's... Same Clan, Different Lineage. My Best Friend & Love of my life (she didn't know) was Jeanne Murphy. None of the names you show here were in her family line. I suggest that you contact the County Seat for Berkshire County, which is Pittsfield, MA & ask for the County Clerk. They have ALL of the Birth, Death, Marriage & Land Records Dating back to 1651, the year that Pittsfield was Founded.
To find the locations more easily, I suggest that you go to Google Earth and Download it onto your computer. If you need help, just E-mail me and I will help you as I know that area so well. Heck, My Mom went to St. Joseph's Church.
