Sarah Henrickson

Played by Amanda Seyfried

As Bill's oldest child, Sarah Henrickson has seen a lot of changes occur in her family. Growing up she was called upon to perform many of the same duties as her father's sister-wives, including cooking and babysitting, and she has, in turn, learned about many of the burdens and stresses of polygamy.
