Earp Family members featured in Wynonna Earp.
Josiah Earp was presumably the son of Wyatt Earp. He was described as courageous by Jack of Knives/Jack the Ripper.
Edwin Earp was the great grandfather of modern Earp Sisters (Wynonna, Waverly, and Willa). He was described as being ambitious by Jack of Knives/Jack the Ripper. Wynonna referred to him as the 'One year Wonder' stating that he was only the heir for 11 months, but almost killed all 77 revenants. This is perhaps what he was so 'ambitious.'
