Although her surname is Western, she is fully ethnically Chinese who was raised in the United States by adopted parents - her Taiwanese aunt and American uncle (hence the Krusiec surname). Her Taiwanese parents sent her to live with her aunt when she was five, so that her mother could better cope with Krusiec's two other siblings. In Taiwan, she is better known by her Chinese name, Yang Ya-Huei, with Yang being her biological father's surname.
