In the late 1980s Graves was involved with tenor Fernando del Valle. She later married guitarist David Perry in 1990, but the two divorced in the early 2000s. Graves then had a relationship with French composer and clarinetist Vincent Thomas. After breaking up Graves discovered she was pregnant, something she thought was impossible because she had been told that fibroids and other conditions prevented her from getting pregnant. In June 2004, she gave birth to Ella (named after Ella Fitzgerald) via emergency C-section in Paris. In June 2006, she met Robert Montgomery, a Johns Hopkins doctor, on an airplane from Dulles Airport to Paris. They were married on June 29, 2009, in a family-only affair. In August the couple travelled to Kenya for a tradition Maasai blessing and had a five-day wedding celebration in September that featured a kick-off party in a private airplane hangar, a rehearsal dinner at their home, a reception at the Anderson House in Dupont Circle, and a day-after picnic on the grounds of Duke Ellington High School. Montgomery is now the Chief of Transplant Surgery at Johns Hopkins Medical Center. The couple resides in Bethesda, Maryland.
