After drifting back into private life and away from public scrutiny, the couple sold their home in Kenwood and then moved to Arnold. In 1977, they moved to Rancho Mirage.
The Agnews returned to Ocean City each summer, staying in an 11th–floor apartment they owned in the English Towers.
Even though her health had been in decline in recent years, Mrs. Agnew kept in touch with old Baltimore friends, some of whom went back to her days at Forest Park, her daughter said.
"She was a warm and caring person who treated all people the same, whether it was a head of state or a mailman," Ms. Sagle said.
"She was just interested in people, and they opened up to her. People would come up to her in the mall and talk to her. Her former Secret Service agents came to visit, and three attended her memorial service," her daughter said.
Mr. Agnew died in 1996 and was interred at Dulaney Valley Memorial Gardens in Timonium, where Mrs. Agnew will also be interred. Plans for Mrs. Agnew's interment were incomplete Thursday.
A private service was held Sunday at Forest Lawn Mortuary in Cathedral City, Calif.
In addition to her daughter, she is survived by a son, James Rand Agnew of Fort Myers, Fla.; two other daughters, Pamela DeHaven of Hagerstown and Kimberly Fisher of Cupertino, Calif.; six grandchildren; and eight great-grandchildren.
