May we go forth together as prophets and friends of God.
Sister Rosemarie Kieffer, known also as Sister Mary Valentine, was born on February 24, 1941, in Chicago. She was one of five children born to Valentine and Mary (Maggs) Kieffer. Her four siblings were Philip, Anthony, Lauretta and Grace.
Sister Rosemarie received her elementary education at St. Columbanus and Our Lady of Peace schools. It was during her senior year at Aquinas High School that she seriously considered her vocation. She wrote the following about her family and her vocation.
I am Catholic to the core. My Dad’s three brothers were priests and he studied to be a priest. We were the family that prayed together (the rosary) and stayed together. I considered becoming a religious for several years and after attending the Reception in Adrian last December  I have become more determined than ever that I would like to become an Adrian Dominican.

I remember Sr. Valentine as my one of my teachers at St. Gabriel School when I was in 6th grade. Sister taught the combination 5th/6th grade class.She was only stationed there one year and was moved to St. John Bosco School in Redford in 1962. We later caught up at Our Lady Gate of Heavenwhen I was filling in for the Organist there some 25 years later.
Our Adrian Dominican cemetery with its circular headstones is a beautiful place of rest for women who gave their lives in service to God—and a peaceful place for contemplation and remembrance.
