Norman Rockefeller, son of Godfrey, was born in Barrington, Columbia county, New York, October 17, 1812. Taking kindly to the independent life of a farmer, and acquiring proficiency in that calling, he settled upon a farm in Richford, Tioga county, in 1840, and resided there some eight years. In 1848 he removed to Phelps, Ontario county, and resided in that town for the remainder of his life. He was an able and successful farmer, energetic, ambitious and possessed sound judgment in business affairs. He was at one time quite active in public affairs, serving with ability and credit in various town offices, including those of assessor and road commissioner. His upright character and genial disposition gained the esteem and good-will of his fellow-townsmen. His ninety-second birthday, which occurred October 17, 1904, was fittingly observed, and his long and useful life terminated in 1905. In 1840 Mr. Rockefeller married Miss Christina Blakeman. She died in 1882. Their children are: Arabel B., born in Richford, New York, July 4, 1841; Ira P., see forward; Ida M., born in Phelps, married Clayton T. Bradley.
