Relatives of Debbie Reynolds and Carrie Fisher are hoping to organise a joint memorial service for the pair as tributes continued to pour in following their deaths.
Singin' In The Rain star Reynolds, 84, died from a suspected stroke on Wednesday, just a day after the death of her daughter Carrie, 60.
The Star Wars actress died in hospital after suffering a heart attack on a flight from London to Los Angeles on December 23.
Fisher's brother Todd said funeral plans were being made and it was "likely" his mother and sister would share a joint memorial service.
He told the New York Daily News: "It's what we want to do, but we're still working on the mechanics.
"We like the idea, if it's at all possible. I think it's appropriate."
Shortly before she fell ill, Reynolds had expressed an interest in laying her only daughter to rest at the spot where she planned to be buried, Mr Fisher added.
He had earlier shared a drawing of his mother and sister, in which they are depicted embracing each other as their most famous movie characters.
The sketch, posted on Mr Fisher's Twitter account, shows his sister Carrie dressed as Princess Leia from Star Wars and Reynolds in a raincoat as Kathy Selden from Singin' In The Rain.
He wrote in the caption: "This is a beautiful love story to witness in my 58 years. I miss them both so much. Love is everlasting."
Meanwhile, the stepfather to Fisher's only child Billie Lourd penned a heartfelt message saying he was "honoured" to be part of her family following the loss of her mother and grandmother.
Bruce Bozzi, who is married to Fisher's ex-partner Bryan Lourd, posted a photo of Scream Queens actress Billie, 24, with Fisher and Reynolds at her university graduation ceremony.
He wrote: "It's an honour to be your stepfather.
"As Carrie said to me years ago 'I'm a good stepmother' I promise I will always be & the strength of these women live so vibrantly in you."
Mr Fisher announced Reynolds' death on Wednesday as he revealed her last words were about her late daughter.
"She said, 'I want to be with Carrie'," he said. "And then she was gone."
