Born Rose Marion in Brooklyn, she entered the congregation in 1934, from Corpus Christi parish, Mineola, L.I.
She taught elementary grades at St. Aloysius, Ridgewood, 1936-52; Holy Spirit, New Hyde Park, L.I., 1952-55; St. Patrick, Huntington, L.I., 1955-60; Our Lady of Perpetual Help, Lindenhurst, L.I., 1960-68; and St. Joseph Mountain School, Monticello, N.Y., 1968-70.
For 24 years, she served as head of the math department at St. Martin’s School, Amityville, 1970-94.
When she retired from teaching in 1994, she began a new ministry along with Sister Agnes Wassmer, O.P., as “The Dynamic Duo Volunteer Team,” serving St. Martin’s School in various ways.
Diminishing health eventually necessitated a move to Carlin Hall.
She is survived by her sister, Helen, and brother-in-law, Stanley Backel, of Florida.
