Mr. and Mrs. Charles William Patton of San Diego, California, have announced the engagement of their daughter, Denise Louise to John Augustine Chilton Hearst.

The bride's father, founder of C. W. Patton & Company, is an acoustical engineer. His family, California pioneer mining engineers, was associated with early California mines, principally in northern California and southern Nevada.

Mr. Hearst's father, William Randolph Hearst Jr., is Editor-in-Chief of the Hearst newspapers and Chairman of the Executive Committee of the Hearst Corporation. Young Mr. Hearst is the grandson of the late William Randolph Hearst, founder of the Hearst communications empire, and the late Millicent Willson Hearst. His great-grandfather, Senator George Hearst, a partner in many mining bonanzas, rode on horseback to California as a Forty-Niner from Missouri. The Senator's wife, Phoebe Apperson Hearst, among many educational and philanthropical accomplishments, helped organize the University of California, the Parents Teachers Association, The Travelers Aid and the National Cathedral School.

The future bridegroom's mother, Austine Hearst, was a columnist at the Washington Times Herald for many years. On his maternal side he descends from colonists long established in Virginia by the time of the American Revolution. He is named for a revolutionary ancestor, Captain John A. Chilton, killed defending General Washington's retreat after the battle of Brandywine.

The prospective bride graduated from The Bishop School of La Jolla and received a bachelor of science degree from The California Polytechnic University.

Her fiance, known as Austin, is an alumnus of St. David's School in New York and the Canterbury School in New Milford, Connecticut. He received a bachelor of science degree from The California Polytechnic University. Mr. Hearst, an environmental consultant and landscape architect, is preparing an environmental study for the Hearst Corporation and is based in the Corporation's San Francisco office.

A late December wedding is planned.
