There's an article in National Genealogical Society Quarterly, June 1965, Vol. 53, Pt. 1, No. 2 about William Demun's Justice of Peace Docket. He was a J.P. in Tweksbury Township from June 10, 1813 to Nov. 1817. A total of 321 cases are recorded in this docket and the article lists the surnames. These cases are not related to marriages but pertain to financial judgments, etc. I'm willing to do look-ups from the list of surnames.
