On The Waltons, she played Mrs. Flossie Brimmer, a widow who ran the boardinghouse. Like Will Geer, who played grandfather Zebulon Walton, Marlowe died between the end of the 6th season and the start of filming for the 7th season. Also, as with Geer, the role was not recast, and the first episode of the 7th season made reference to the character’s death. As it is mentioned that it has been 6 months since Zebulon Walton died, it’s revealed that Flossie died somewhere in that timespan, in 1941. Viewers were made aware of her death by a scene in Ike Godsey's store. Olivia Walton receives a package from Patsy Brimmer, Flossie's niece. The package contains Flossie's cameo ring, and a note from Patsy stating that she felt Flossie would have wanted Olivia to have it, and a request to think of Flossie when it was worn. The Baldwin sisters, Miss Emily and Miss Mamie, Corabeth Godsey, Ike Godsey, and Olivia then reminisce about Flossie, and Miss Emily comments that the boardinghouse is now boarded up. Later in the episode, it is revealed that one of the boarders, Zulilia, known for flirting in past episodes with Zebulon Walton, purchased it, with plans to reopen it.

In addition to National Velvet, she and James McCallion appeared together in Wagon Train and The Big Valley.^[3] They had two children, Denis McCallion and Tracey McCallion Campbell.^[4] Their son later became a television producer,^[5] and daughter Tracey worked as a personal assistant to many people in the entertainment industry.^{[citation needed]}
