Indeed there was a Massachusetts state census for 1855 and 1865 and it was for everyone in the state not just the Irish. Apparently, someone extracted the "born in Ireland" information from the 1855 census and indexed those people. Also, to my eye, the towns that are listed on that site are in the western part of the state and represent only a very small percentage of the cities and towns that existed in 1855. The entire 1855 census is at the MA Archives and I'm thinking that the LDS has filmed it also. Joanne
