There's a woman in Lakeville who has documented all the gravestones and their inscriptions in the town of Lakeville. I thought that Pa Leonard, considering all his work as Lakeville Cemetery Commissioner, would appreciate this labor of love. I helped him one summer organize his files, and Mom did a lot of work with him, too.
Here's an article and a short slide show where the author talks about her work. In them she talks about the gravestone of a child of Elkanah Leonard, a long-departed cousin and grandson of original settler James Leonard. Both were involved in the Taunton ironworks.
