John Ridgely III, 79, a direct descendant of the builder of Towson's 18th-century Hampton Mansion and the last to live on the estate, died of congestive heart failure Sunday at College Manor.
A memorial service will be held at 2 p.m. tomorrow at Trinity Episcopal Church, 120 Allegheny Ave., Towson. Burial will be in the Hampton burial grounds.
Mr. Ridgely had lived since the late 1940s at his home, Spring Hollow, which he built on the Hampton property. The house was built about the time his father turned over the Hampton Mansion to the National Park Service in 1948.
Mr. Ridgely retired about 10 years ago as a salesman for a printing company, Arthur Thompson & Co., with which he had been associated for many years.
He became an active supporter of the Hampton National Historic Site, serving as a director of Historic Hampton Inc. and donating family furnishings for exhibiting in the mansion, which dates to 1790.
A resident of the Hampton area all his life, he was a graduate of the Gilman School. In 1935, he married the former Lillian Ketcham. They lived in the mansion and also in an older farmhouse on the estate, Huntsman's Lodge.
During World War II, Mr. Ridgely served in the Army Air Forces in the Pacific, and his wife was an Army nurse.
In 1958, he ran unsuccessfully for a seat on the Baltimore County Council.
He was a subscriber of the Bachelors Cotillon.
Besides his wife, survivors include a sister, Louise Roman Ridgely Buckingham of Sheridan, Wyo.; and several nieces, nephews and cousins.
