Clare Marie Mosmiller, a homemaker who was active in Roman Catholic educational charities, died of leukemia Thursday at her Catonsville home. She was 70.
Born Clare Marie Synan in Baltimore and raised on Marydell Road, she attended St. Joseph's Monastery Parochial School and graduated in 1955 from Seton High School, where she played basketball. As a teen, she worked at the Eckhardt Pharmacy in her neighborhood and at the old Stewart's department store in downtown Baltimore.
In the early 1950s, she met Joseph W. Mosmiller. Family members said their first date was at the Alcazar Ballroom at Loyola High School's annual Easter Monday dance.
They married Aug. 10, 1957, her 20th birthday, while her husband was a Mount St. Mary's College student. He went on to become president and later chairman of the old Loyola Federal Savings and Loan Association.
As a young woman, she also worked at Central Savings Bank, at Charles and Fayette streets. She stopped working to raise her family.
"She stood up for herself and for what she thought was right," said Marian Kalmbach of Arnold, a lifelong friend. "She knew how to conduct herself and to speak in a kind and not-affected way. She would not back down when she thought something was wrong."
Mrs. Mosmiller volunteered at St. Mark's Parochial School in Catonsville in the early 1970s and was president of the mother's club when her children attended school there. She was a member of the board of Archbishop Keough High School, where she ran silent auctions and collected prizes and gifts.
In recent years, Mrs. Mosmiller was a donor to Sisters Academy of Baltimore, a Roman Catholic middle school for girls from Southwest Baltimore. She and her husband endowed a scholarship to the Lansdowne school, where a memorial fund has been established in her name.
"She visited the school and sponsored a student with whom she corresponded by mail," said her daughter, Sheila Vidmar of Catonsville. "She was excited about educating these girls in a quality setting."
Mrs. Mosmiller collected antiques and seashells from the beach in Naples, Fla., where she had a home. She also solved crossword puzzles and worked jigsaw puzzles.
A Mass of Christian burial will be offered at 11 a.m. Tuesday at St. Mark Roman Catholic Church, 30 Melvin Ave. in Catonsville, where she was a member.
In addition to her daughter, survivors include her husband of more than 50 years; two sons, John J. Mosmiller of Towson and Mark A. Mosmiller of Finksburg; another daughter, Susan Mosmiller Elliott of Ellicott City; and 10 grandchildren.
