Maggie Walker question

Just a handful of credits over a four-year period, including the only decent performance in SCREAM AND DIE/THE HOUSE THAT VANISHED, where she had a very memorable full frontal sex scene with a much younger man. She was probably early 40s then, shot in 1973, which would lead one to believe she is likely no longer with us in 2024. But after seeing a few other more conventional things she did, I’m assuming she had to have been a professional stage actress, as even in small parts she was very good, and she had real presence. That said, she’s one of these people who seems to have no biographical information anywhere on the web, including an obituary. Any information would be welcome as there are quite a few of us who are fans of Jose Larraz and his films that are curious. Thank you in advance.
