It was Sr. Mary Gongaza who introduced me to her very dear friend Helen. We had many very lovely visits when she came to see Sr. Mary Gonzaga. Helen was a very gentle, loving person. I remember meeting Mary Ellen. What a glorious moment for Helen to be greeted by Jesus and Sr. Mary Gonzaga on her arrival in heaven. Peace to Helen and her family.
All my love, prayers and unity., Sister Susan

Mary Ellen,
I am so sorry to learn of your loss of your mother. I know you were very devoted to her, and looked out for her well-being in spite of your many other responsibilities. She must have been so proud of you and all you have achieved, as it sounds as though she also achieved in her lifetime.
I hope at this new year begins, that you are comforted in knowing that your care mattered, and that she is now at peace.
I hope we can talk more at a club run, if you would like to do that.
With sympathy and a hug,
Barb Day
