  2. I am sorry to hear of Cort’s passing. He and Nancy were the most wonderful of family friends, meeting them when they were building their home in Mystic all those years ago. Cort was a gracious and kind man, and we will all miss him. Tracy Jackson Heffron

  4. You probably don’t remember me but I remember your father and mother as your dad worked with my dad -the Doc- at EB and then at the Underwater Sound Lab. I look at the picture of your dad and he still had that lovely and kind smile. I remember parties and dinners at my parents house in Niantic where your parents were in attendance. Your father always took the time to talk to me and showed an interest in how I was doing. As a young girl your dad made me feel grown up and important. And then, I also married a Coastie. Your parents came to our wedding. Even more coincidental was that Larry was stationed in the Aleutians as the CO of a loran station. We would see your parents at CGA reunions. We always made sure to visit and catch up with them. I have fond memories of both of your parents. Please accept our deepest sympathies for the loss of such a lovely man – a husband, father, grandfather, and great grandfather. Love, Margreet (Van Woerkom) and Larry Beason
