    Cousin Kathy, As stated by my siblings, so many happy and very funny memories you have left us with. All the wonderful times we were all able to share at 160 Boston Street. Your favorite snack of Coca-Cola and CHEEZ-IT's and occasional Devil Dog. We will all remember the unforgettable St. Patrick's Day several of us attended at the AOH in Salem one year! Here's to you and many, many long walks you can once again take with your Dad. I'm sure your whole family (and extend family) welcomed you with open arms and big hugs. Rest In Peace with the Angels, God Bless Love, Betsy and Brian

    I remember going up to the camp with her. During breakfast we wore sunglasses because the sun was so bright. RIP Kathy.
