Who Is Phyllis Gilliam? ‘Georgie & Mandy’s First Marriage’ Tribute Explained

Georgie & Mandy’s First Marriage‘s Season 2 finale made way for a special tribute in the first half of its two-part run, as a title card ran a dedication for Phyllis Gilliam.

The title card read, “In loving memory, Phyllis Gilliam, January 26, 1956 – March 23, 2026. But who was Phyllis Gilliam? She worked on the Young Sheldon spinoff as a costume supervisor, working on both Seasons 1 and 2 of the CBS comedy. According to an obituary, Gilliam, who started in Hollywood working as a costume designer in the 1980s, died after a Stage IV cancer battle.

“Phyllis found herself in the ICU. Surrounded by friends and family who poured over her with love, reminiscing about their favourite moments with this beautiful woman, watching It’s a Wonderful Life – Phyllis’s favourite movie. On March 23, 2026, Phyllis took her last breath. On that day, the world was a little bit less light,” the obituary read.

The obituary also revealed that Phyllis’s cancer battle coincided with that of her late husband, Murray Gilliam. He died following his own battle with cancer in January 2026. Phyllis and Murray left behind two children, Susan and Robert, the latter of whom posted a GoFundMe.
