The CW has an 1800s-set Walker prequel spinoff in the works: Walker: Independence

Deadline

Walker creator Anna Fricke and star Jared Padalecki are executive producing Walker: Independence, based on a story by her and Walker executive producer Seamus Fahey, who will write the potential series. "A Walker origin story set in the late 1800s that follows Abby Walker, an affluent Bostonian whose husband is murdered before her eyes while on their journey out West," reads Walker: Independence's logline. "On her quest for revenge, Abby crosses paths with Hoyt Rawlins, a loveable rogue in search of purpose. Abby and Hoyt's journey takes them to Independence, Texas, where they encounter diverse, eclectic residents running from their own troubled pasts and chasing their dreams. Our newfound family will struggle with the changing world around them, while becoming agents of change themselves in a town where nothing is what it seems." It is unclear if/how the 1800s' Abby Walker and Hoyt Rawlins are related to present day’s Abeline Walker (Molly Hagan) and her sons, Cordell Walker (Padalecki) and Liam Walker (Keegan Allen), as well as Cordell’s best friend Hoyt Rawlins (Matt Barr).
