According to Ann Humphreville, her great-grandfather and his brother worked in one of Peter Crosby Barnum's men's clothing stores in New York City from 1865-1872. Her family has hundreds of letters addressed to and sent from the brothers at the store's address, many of them concerning the business. The brothers, Asa and Charlie Dutton, finally left P.C. Barnum's employ when they bought into an existing store on the Bowery. Barnum's store was located at 196 Chatham Square, in the City.
The two Dutton brothers moved back to the Albany area in retirement and in 1964 when their granddaughter (Ann Humphreville's aunt) cleaned out their house, she found a receipt from the P. C. Barnum business for a suit that had been sold to General Tom Thumb.
