More than 1.4billion names are held in the database, which includes many important collections for tracing Irish emigrants to the USA, and their descendants. Among them are the Massachusetts, Archdiocese of Boston RC registers, 1789-1900, which is growing at one heck of a pace while NEHGS volunteers index the volumes, parish by parish; censuses; bmd announcements in local newspapers; probate and vital records; immigration records and much more. The free access runs until close of play on Tuesday 17 July.
