Our earliest Groton ancestors, i.e. Lawrences, Tarbells, Parkers, and others who preceded Samuel and Susanna Lawrence, are interred in the Old Burying Ground in the center of town. (Many of the graves are worn and illegible, but Samuel Abbott Green compiled an interesting book of the headstone inscriptions there, Epitaphs from the Old Burying Ground in Groton, Massachusetts.) The Old Burying Ground is located here.
Our more “recent” kin, recent by New England standards, starting with Samuel and Susanna Lawrence, are buried in the Groton Cemetery, a little further towards the outskirts of town.
Both of these places are well worth the trip.
