Biographical / Historical

Jesse Darlington (1762-1842) settled in Midddletown Township in Delaware County about 1797. He married Amy Sharples at Middletown Meeting (Chester Monthly Meeting) in 1787, and they had ten children. Jesse Darlington was a dairy farmer, and his youngest son, Jared Darlington (1799-1862), went into partnership with his father in the business of farming and butter making. They labeled the butter as "The Darlington" and "The Cornucopia." Two of Jared's sons, Jesse (1841-1912) and Jared (1844-1902) assumed the farm as J and J Darlington. They were succeeded in the business by two of Jesse's sons, Jared Worrall Darlington and Paul Darlington. At it peak, Cornucopia Dairies served hotels in New York and Washington, D.C., but their dairy became a casualty of the Great Depression.

Jared Worrall Darlington (1875-1934) married Hannah Mary Sharples in 1899. Both attended Swarthmore College. Jared was appointed postmaster of the Darling post office in 1898, and after his death, he was succeeded by their daughter, Martha Darlington. She had graduated in 1930 from Penn State College's program in Architecture.
