The term French Sisters can refer to two different sets of sisters. The first set is the Soeurs, a group of four French sisters who were born in the late 19th century and early 20th century. They were all highly educated and had successful careers in the arts, sciences, and politics. They were also active in the French Resistance during World War II. The second set of French Sisters are the Soeur Sourires, a trio of French nuns who were known for their work with the poor and sick in France during the 1960s and 1970s. They were also known for their music, which was a combination of traditional French folk songs and modern pop music.
