Built circa 1873, the John Newberry King House is a French Second Empire-style residence located at 793 Main Street in South Windsor. It was built for John Newberry King (1822-1895). According to the second volume of the Commemorative Biographical Record of Hartford County (1901):
Hon. John Newberry King, son of Roderick King, and the father of Isaac White King, was born March 24. 1822. He married, Dec. 25, 1848, Julia Ann, daughter of Isaac and Adocia (White) Keeney, and a direct descendant of Perigrene White, who, it is said, was the first white child born after the landing of the Pilgrim Fathers. Mr. King was one of the first to introduce tobacco growing in the town of South Windsor; was among the first to build tobacco sheds, and to engage extensively in the cultivation of that plant. He was one of the substantial men of his period, a man of good ability, excellent judgment and an all-round good and useful citizen. He was a farmer all through his active, busy life, which was lived in a manner worthy of his New England ancestry, and which is to the credit of his posterity. For many years he was active and prominent in the councils of the Democratic party of his section. He served that party on its central committee and in 1879 represented his town in the General Assembly of the State. He was prominently identified with the Masonic Fraternity, and was the principal mover in organizing Evergreen Lodge, No. 114, F. & A. M., of which he was a charter member, and for a number of years its worshipful master. He was successful in the management of his business interests, and accumulated a competence, holding considerable property mostly in his town, also in East Hartford. Mr. King died in 1895, aged seventy-three years.
