Ettie Edwards, née Shafter, was a woman mentioned in The Valley of Fear. She was the daughter of Jacob Shafter, a German immigrant who managed a boarding house in Vermissa. She married Birdy Edwards (alias John McMurdo), a Pinkerton detective who travelled to the valley in disguise to investigate the Scowrers. Because the Scowrers wanted revenge on Edwards, they moved frequently and changed their names.
