An unknown "Negro girl" was enslaved by Johnathan Stone, and included in his estate.

Frost's abstract of the probate record for Jonathan Stone includes "A Negro girl at £40." The abstract does not indicate who inherited this girl. (Note: the abstract references are dated 1756; is this the same Jonathan Stone who died in 1739?)

"A few of the inhabitants of Arundel were able to hold slaves. Mr. Prentice bought the first one owned in town, in 1734. Mr. Hovey also owned one, and probably sold him in 1747. Robert Cleaves, Thomas Wiswall, Samuel Hutchins, John Fairfield, Gideon Walker, Andrew Brown, and Jonathan Stone each owned a slave. Several of them were living in the town, but a few years since, the last two of whom died in the poor house, or which the son of the former master of one of them was an inmate." - Bradbury, p. 158

The "old brick," a building on Main St in Kennebunk that had a succession of owners and prominent tenants "was sold to Jonathan Stone of Kennebunkport, who converted the "annex" into a public house, the "Mousam House." It was a well-arranged and well-kept establishment, but Mr. Stone's health would not permit him to perform the duties of landlord, and within two years from the date of assuming them he relinquished the business and returned to his native town, where he died May 29, 1839, aged forty-seven years." - Remich, p. 347
