I don't know the exact date of Gwaldys death but am guessing it was between 1949=1950. She divorced Homer Hyde I'm guessing somewhere in the late 30s and married my father in the early 1940s. She was deceased by sometime in 1950 when my parents met. My father married my mother in 1951.
Know that Gwaldys owned a 1930 Arnold Dolmich clavichord and took three of her students to England in the late 1930s to hear the Dolmich family perform. Suspect that she knew the Dolmich family and may have even performed at the festival.
