St. Paul's Episcopal church bought the one-story brick school edifice for its first church building.

The evidence

• “Mr. Leonard Humphrey's school was held in a one-story brick building, which he had built, twenty by thirty feet, on the ground facing north on Public avenue, now number 534, and was called "the aristocratic school." In 1844 that edifice was bought by St. Paul's Episcopal church and used as its first church building.”
