Before her death, she was one of the two Heirs. Following her death, Wynonna Earp remained the sole Heir.
Willa Earp was born on October 07, 1987 and is the eldest daughter of Ward Earp. Being the eldest, she was originally supposed to be the Heir and was trained from childhood by her father. After her father's death and her abduction on September 7, 2000, she was presumed dead and the responsibility went to her younger sister, Wynonna Earp.
Willa was originally thought to be dead, but Bobo simply told all the revenants that he killed her. In reality, he hid her away, protecting her for years. Over that time, he slowly developed feelings for her, and her for him.
Relationship: Lovers; both deceased
Bobo saved Willa from The Seven and other Revenants at the time of Ward Earp's death. They eventually fell in love over the 16 years they spent together. Their relationship came to an end when Constance Clootie freed Willa and wiped her memories. Wynonna eventually brings Willa back to Purgatory and she later gets her memories back (including those of Bobo). They restart their plan of crossing the Ghost River Triangle together to free the revenants and be together. Wynonna ends up shooting both of them with Peacemaker, effectively ending their relationship.
Relationship: Sisters; Pals
Willa and Wynonna were very close as kids. Willa describes them as being "peas in a pod". Wynonna grieved for Willa when she thought she died as a kid. Wynonna is also the who saves Willa from Lou. They rekindle their sisterly friendship when Willa regains her memories until her plotting with Bobo gets in the way. Wynonna didn't want to shoot Willa even though she betrayed them. She likely only shot Willa since Dolls already had and wanted to put her out of her misery.
Relationship: Sisters; Estranged
Willa and Waverly did not get along very well as children. Waverly claims that Willa once caught her sneaking through their dad's things, so Willa made her walk across a far up beam. Even once Willa is rescued and her memories come back, they still end up fighting and Waverly seems unsure of Willa's return. The worst of it happens when Willa shoots Waverly's girlfriend, Nicole Haught, so that she can get away with Peacemaker.
