  1. Funny, I was just talking about Margaret recently and telling someone about how I fell in love with her when I worked at Nadeau’s Pharmacy as a kid, and she, the most elegant lady I’d ever met, found escape and solace and pleasure, (it seemed anyway!) feather dusting items on the shelves. I appreciated the way she treated me when I was a silly teenager, with respect and kindness, always welcoming me into her home. I am truly affected by her passing…it’s a terrible loss. Rest in peace, Margaret. I will never, ever forget you.

  2. To Albert and family, It saddens me to hear of Margaret’s passing She was the best godmother anyone could have.Generous and loving. Margaret,was my mom’s BFF.My prayers are with you all.Rest in peace Margaret and have a drink with mom.

    When we would visit at mailbox, you were such a wonderful gift to know. I always blew you kisses when I saw you leave or coming home in your car. The love that came from your presence filled me with joy and peace. Your beauty was incredible both inside and out. You are smiling at us while walking with Jesus and our Father. You must lite up heaven more than it already is. Love.
