Named for Rose Marie Mauch (b. 1942) by her parents Henry (1894-1986), a German-American Angeleno, and Cacilie (1907-1998), a German immigrant. Henry and his family settled in Arcadia in 1922, buying five acres at the northwest corner of Palm and Holly and raising chickens and berries. He married Cacilie Meurer in 1932 – she had come to Monrovia just a year or two earlier – and they had four children: Rita, Richard, Rudy, and Rose Marie, the baby. The eastern half of Rosemarie Drive was christened by the Mauchs when they subdivided their acreage in 1953. (The western half was added by other landowners in 1956; the two never connected.) I couldn’t find out much about Rose Marie herself. She attended Holy Angels School and Pasadena City College, then married Robert W. Turner in 1966 and moved to Rowland Heights.
