From "History of the Town of Groton, including Pepperell and Shirley" by Caleb Butler-

There have been erected in Groton seven houses, purposely for places of public worship, exclusive of those in Pepperell and Shirley....... A vote also passed, September 23, 1663, "That John Nutting shall keep clean the meeting-house this year, and for his labor he is to have fourteen shillings". The meeting-house here mentioned must have been the minister's house, as none other was yet built, as appears by the following vote.

"At a town meeting, upon the 21st of the 7th month, 1665. It was this day agreed upon, that they will have a meeting-house forthwith."
