Analysis of information sources in references of the Wikipedia article "Brushy Bill Roberts" in English language version.
Oliver P. Roberts was Brushy Bill's name. I don't know what the P was for. He was born Aug. 26, 1879. I have the family Bible record.
William Shafer, Bill Jones' grandson, wrote on July 9, 1950: "I am sorry, but Mr. Jones does not feel that he can sign your affidavits that your man is Billy the Kid. He gave no conclusive proof of this at the time we met him. It seems to me that if he were Billy the Kid he would not need affidavits to prove his contention.
