Catherine Littlefield is born on September 16, 1905, and takes her first dancing lessons from Caroline (Mommie) at the PRR-YMCA in 1908. Mommie also teaches Jeanette MacDonald and stages recitals along with her husband (Big Jim). The Littlefields live for a time in Ambler, Pennsylvania, and later in Philadelphia, and have three more children: Jimmie, Dorothie, and Carl. As a young girl, Catherine also takes lessons with Philadelphia dancing master C. Ellwood Carpenter and performs in his ballet corps. Mommie helps Carpenter teach. Big Jim works as a lifeguard in Ocean City, New Jersey, and operates the Littlefield Riding Academy in Philadelphia. The Littlefields move to Llanerch, Pennsylvania. Big Jim serves with the YMCA in World War I.
