Josepha Johnson was the sister of Lyndon Johnson. The statuesque beauty had affairs with both John Kinzer and Mac Wallace. She did not get along with her brother and did not approve of his business dealings. Beyond this, she was quite vocal about her opinion.

It was through Josepha that John Kinzer requested a rather large loan. Lyndon took the request as the beginnings of a blackmail effort and it led to his untimely demise at the hands of Mac Wallace.

Her demise was not far behind as she died in her sleep. The coroner ruled the death was the result of a cerebral hemorrhage even though no autopsy was performed. After he fell from favor, Billie Sol Estes claimed this was not the case.
