The prolific actress also appeared on popular shows like “How I Met Your Mother,” “Mad Men,” and “Monk.”

Marcia Ann Burrs, the veteran actress whose decades-long career included roles on TV shows like Young Sheldon and It’s Always Sunny in Philadelphia and in two Hallmark movies, died Sunday at 85.

Her family said in a death notice that Burrs died peacefully while surrounded by loved ones. A cause of death was not specified.

Joking that Burrs never considered herself a day over 39, her family described her as a “much-loved wife, mother, grandmother, and lifelong performer” who “lived with heart, humor, creativity, and an unapologetic toughness that brought authenticity to every role she played on screen and in life.”

Born Marcia Hoffman on Nov. 25, 1940, in Manila, she gravitated to the stage from a young age and went on to study drama at the College of William & Mary in Virginia. She later relocated to New York City, where she began taking roles in commercials, on soap operas, and on the stage.

After meeting and marrying Joseph Edward Bures, she took on the stage name Marcia Burrs and moved to California. A working actress with an impressive resume, Burrs made guest appearances on several popular shows, including Moonlighting, 7th Heaven, Will & Grace, Gilmore Girls, Frasier, Monk, The King of Queens, My Name Is Earl, Scrubs, Bones, Criminal Minds, How I Met Your Mother, and Grey’s Anatomy.

In a fan-favorite season 2 episode of It’s Always Sunny, Burrs appeared as Angie Spinola, the former high school girlfriend of Danny DeVito’s Frank. Years later, she guested on Young Sheldon as Betty, a cousin of Meemaw (Annie Potts) known for giving cheap gifts.

On the big screen, Burrs had roles in the Jennifer Aniston-led rom com Rumor Has It and Sofia Coppola’s The Bling Ring.

Burrs was perhaps most recognizable for her role as Mrs. Claus in the beloved Hallmark holiday films Single Santa Seeks Mrs. Claus and its sequel Meet the Santas, which saw her star alongside Steve Guttenberg and Crystal Bernard.

Her death notice said that “though she loved performing, her favorite role was Mom — the one she cherished most. She taught her kids that life was limitless, rules were optional, and you could do anything. She lived it, she meant it, and she passed it on like a family superpower.”

Burrs was preceded in death by her husband. She is survived by two brothers, a sister, daughters Jennifer Martin and Diana Fuller, and grandsons Grant Joseph Fuller and Talon James Hartsell Fuller.
