I want to know the answer to the following question:
What famous American traitor has a first wife buried in a 17th century crypt in a New Haven church flanking New Haven Green?
All the background I'm provided with is that "Some of the more famous burials include the first wife of Benedict Arnold and the aunt and grandmother of President Rutherford B. Hayes; Hayes visited the crypt while President in 1880.". Is that enough to answer the question?
