I think that Gladys Luloff Hyde died prior to 1958. I attended a memorial concert, about 1952. with my mother, cousin of Gladys & we met Glady's father (my mother's Uncle) there. There was a large painting of her in the lobby.
The obit says sister of Ralph & Julia Metivier. Glady's parents were married until her her mother died & her father never remarried.
