How many times was Tate married, and how many children did she have in the biography, The Flight of Red Bird: The Life of Zitkala-Sa?

Gertrude was one of Tate's nine children from three marriages with white men. Only five of Tate's nine children survived. Three older sons from the first marriage were grown and lived nearby. David, 12, was from Tate's second marriage. Gertrude was from her third marriage. The U.S. government forced Tate to send David to boarding school. She signed the agreement, even though she didn't know how to read.
