Lucy's mother died leaving a large family behind. Joseph told her grieving father to split up the children, he had Lucy and the older children move in with him and then sent Lucy's father on a mission. He proposed to Lucy when she was 17 years old, she was uncomfortable with the idea and didn't have her parents to counsel with, and did end up marrying him. After his death she married Heber Kimball and had 8 children. She died in Salt Lake City.
