I spend a pretty deal of time in the burying place to see to the Graver of the Tombstone: Push Catterpillars off the Apple-trees; goe to the Meeting at Mistress Averyes; read out of Dr. Sibs about submitting to God's Providence, Sing the 110. Psalm.
- Diary of Samuel Sewall, May 4, 1687
From this entry, we learn that the elusive Boston stone carver (or one of his colleagues) sometimes met with clients in the graveyard itself. Since Sewall usually uses the word "tomb" to mean a family tomb and "stone" to mean a gravestone, I suspect that he was overseeing carving on the Sewall family tomb in the Granary Burying Ground on May 4, 1687.
