Charles Wagner was their first booking agent, then they signed on with Frederick Christian Schang. Thinking the name "Trapp Family Choir" too churchy, Schang Americanized their repertoire and, following his suggestion, the group changed its name to the "Trapp Family Singers". The family, which by then included ten children, was soon touring the world giving concert performances. Alix Williamson served as the group's publicist for over two decades. After the war, they founded the Trapp Family Austrian Relief fund, which sent food and clothing to people impoverished in Austria.
