Which Reminds Me

I vaguely remember Karen Ha, who was in music theory with us, a violinist or some type of string player I am thinking, who married John Howell. I seem to remember seeing them again much later in California, perhaps when I was visiting Diamond Bar although I am not sure. After that I seem to remember reading about them working at the Library of Congress but I really don't very much about that. I really don't know them very well. They were just there in the same college so I remember their faces.
