The Hamilton Post Office, (North Kingstown Township, Washington County) was established on February 26, 1877 under Postmaster Benjamin C. Sweet. This post office was disestablished on November 15, 1957 and consolidated along with the Wickford and LaFayette post offices as the North Kingstown Post Office, which is currently in operation.

Hamilton is located just south of Wickford and there was an old mill pond there where I caught many a bluegill and even an occasional bass. The mill has been converted into Condominiums and the North Kingstown High School is just up the old post road, (A1A) from Hamilton.

Benjamin Sweet was born in North Kingstown in 1840 and was married to Emily A. Sweet. His occupation is listed on the 1880 census as grocer and also listed is a son named Arthur B. Sweet. There was an old grocery store in Hamilton fronting on the Post Road that was still going strong in the late 1950s. I can't remember what name it operated under.
