If there was one very touchy subject for Humphreys, it was his daughter Llewella. At a young age, Llewella Humphreys was the victim of severe mental troubles. While in school she had shown fine musical talent, giving her father the idea to send her to Europe where she could further her musical studies but while in Rome Llewella met the Italian actor Rossano Brazzi, and the two became lovers. When Llewella returned to America she gave birth to a son on July 14, 1955, whom she named George Llewellyn Brady. Humphreys sent Llewella and her baby to live in Oklahoma with Llewella's mother; but, in 1958 Murray Humphreys had his increasingly ill and unstable daughter committed to a Topeka, Kansas, sanitarium, where she remained for the next three years.
