    I remember Sister Marcella teaching us songs when I attended summer camp at Cormaria as a young girl. She taught us songs, as we sat outside on the patch of grass between the house and the dock overlooking the bay. I remember her always having her guitar with her. She was fun, and we all loved her. Very sad to hear of her recent passing. I will pray for her and offer up a rosary for her.
    Rest in Peace Sister Marcella.
    With love,
    Maria McCabe (ne: Avila)

    Sr. Marcella was a wonderful religious – and made God known by her life.
    I came to know Sr. Marcella in Rosedale and she always encouraged me to become a priest- she by her love helped me to eventually go to the seminary and become a priest in the Diocese of Rockville Centre.
    Sr. Marcella, may you rest in our all loving God’s arms.
    Know I pray to you daily
    Sincerely in Christ,
