The Roman Catholic Archdiocese of Santa Fe has opened a process to canonize Segale.
Letters that she would write to her sister back east were found and published in to a book titled "At The End Of The Santa Fe Trail" in 1948 by the Bruce Publishing Company of Milwaukee, Wisconsin.
In the book it states up front on pages 11 and 12 "Nor did she quail when she asked Billy the Kid and his gang not to scalp Trinidad's four physicians, although Billy had come to Trinidad for the express purpose of killing these four men."
Note that there is no credible proof, nor other writings, indicating that Billy The Kid was ever in Trinidad nor any place north of Las Vegas, New Mexico nor any of his "gang" raiding on the Santa Fe Trail as this book indicates.
There are several references to Billy the Kid in her book. But we must remember that these references were in letters sent to her sister and really never meant to be published.
From the publication The American Catholic come this bit of information:
"One of the many outlaws who terrorized the area was Arthur Pond aka William LeRoy, sometimes known as Billy the Kid, and who was celebrated as the King of American Highwaymen by the “penny dreadful” novelist Richard K. Fox who released a heavily fictionalized biography of him immediately after his death, conflating his exploits with those of the more famous Billy the Kid. (Sister Blandina in later life confused LeRoy with William H. Bonney, the more famous Billy the Kid, who operated in New Mexico a few years later. Sister Blandina had known the outlaw only by his nickname and didn’t realize that there were two Billy the Kids, who died within months of each other in 1881.)"
Note: There is so much of this fantasy that passes for history in the United States it is hard for the average person not to swallow this stuff..... hook, line, and sinker.
