Now consider the three Roberts signatures shown at the left. The first one is clipped from the above letter. It was likely signed in Brushy’s own hand because it was signed “Wiliam Bonney Billie Kid” just below the name Bill Roberts. His wife didn’t write the letter because he was keeping the Billy The Kid identity a secret from her. The second is also signed by Brushy on the death certificate for his second wife Luticia Ballard. This again was in his own hand because it is clearly marked with a star indicating where he was to sign and later marked with a check mark to the right.
Note the similar slant and proportions of the letters, the way the letter “T” is crossed and the way the letters “e” and “o” are closed in both signatures. Now notice how the third signature has the ending “s” much larger that the other lower case letters and how the “t” is not crossed the same as the first two. Also the small letter “e” and “o” are both open where in the first two signatures they are both closed and the entire signature shows letters drawn more slowly and in the straight up position.
The third signature is from the signature of O.P. Roberts in his divorce from Anna Lee in 1910. O.P. Roberts, or Oliver Pleasant Roberts was married to Anna Lee but Brushy never identified her as one of his wives. O.P. and Brushy were two different people as can clearly be demonstrated by these signatures. This is compelling evidence that Brushy began using the alias of Oliver Roberts sometime after 1910, not long before he married his “first” wife Mollie Brown in 1912. Also of importance here, Brushy signed his name as “Bill” which is short for William and also as “Ollie” which may or may not be short for “Oliver” but both signatures show a more accomplished handwriting than the O.P. Roberts signature as do all of the alleged samples of handwriting by Billy The Kid. So while these samples do not prove Brushy was Billy the Kid, they do prove O.P. Roberts was not Billy nor was he Brushy Bill. Thus the real possibility remains that Brushy and Billy were one and the same.
