Fisher, a longtime mental health advocate, openly discussed her battles with depression and bipolar disorder during her lifetime.
Joely Fisher penned an essay this week in remembrance of her beloved half-sister Carrie Fisher.
Both made their debut to the Broadway stage in 1973 with Irene, a musical comedy revival of the 1919 show, and Fisher was nominated for a Tony Award for her role. "And so they're together, and they will be together her and in heaven, and we're okay with that", he said.
Other guests included Jamie Lee Curtis, who stars with Fisher's daughter Billie Lourd on TV series Scream Queens, singer Courtney Love, and actors Ed Begley Jr, Candice Bergen and Ellen Barkin.
"We'll have a bigger service down the road for the public and all the family friends, but this was a private family service", Todd Fisher said. Her son, Todd, was at the home with her, making arraignments for Fisher's funeral. The funeral saw many famous faces paying their respects at the intimate Beverly Hills ceremony, held at the family compound in the Coldwater Canyon area. While there, Meryl Streep performed Fisher's favorite song, "Happy Days Are Here Again".
"Debbie Reynolds and Carrie Fisher were entertainment legends who delighted fans around the world on stage, on screen and on the page".
Fisher was spotted carrying the urn in Twitter photos from at a private memorial service for his mother, Debbie Reynolds.
Fisher died on 27 December aged 60, having suffered a heart attack while on a flight from London to Los Angeles. Reynolds, her 84-year-old mother and an accomplished actress, died the next day. "All the tributes circled back to Billie and how much Carrie loved her", a source described as a "family friend" told the magazine.
