Mary Jo,

We are so saddened to hear about John’s passing. He was such a wonderful person, always so kind. We loved when we would talk at Church or the grocery store. He always asked about the kids.

We didn’t know of his passing until I read the minutes of the St Paul women’s meeting notes.

We will keep you and your family in our prayers.

From your ‘former’ neighbors and friends

Sending much love your way Aunt Mary Jo. My heart is with you, Alice and Robert and their families at this time of great loss. Uncle Jack was one of the kindest men on earth. His laugh is stamped into my heart for all time. What a happy, kind and generous soul. I will miss him. With Love, Betsy & Phoebe

It was always a pleasure to run into Mary Jo and John, whether at St Paul, shopping, or just out for a stroll. What a lovely, kind, sweet man to know. Steve and I are thinking of you, Mary Jo, and keeping you in our thoughts and prayers.
