In their later years, Wyatt and Josephine Earp worked hard to eliminate any mention of Josephine's previous relationship with Johnny Behan or Wyatt's previous common law marriage to Matty Blaylock. They successfully kept Josephine's name out of Lake's biography of Wyatt and after he died, Josephine threatened to sue the movie producers to keep it that way. Lake corresponded with Josephine, and he claimed she attempted to influence what he wrote and hamper him in every way possible, including consulting lawyers. Josephine insisted she was striving to protect Wyatt Earp's legacy.
