We always called him "Uncle Fate" which was proper since he was my grandfather's brother and my great uncle. I had always assumed his name was Lafayette but when he registered for the draft in 1918, he signed his name as William Granville Montgomery. Granville was the name of his grandfather so that was a good choice. In the 1910 and 1920 census, he is listed as Fayette which ties with the nickname that we used. For the 1920 census, he became William G. and by 1930, he is just W. G. He married his first wife as Lafayette but was W. G. for his second. It seems that "Uncle Fate" has a more complex name than previously thought. I am going with William Granville Lafayette Montgomery to cover all bases. I will still refer to him as "Uncle Fate."
Uncle Fate also used W. G. Montgomery for a marriage license that was issued on April 26, 1919 for him to marry Pearl Scott. This license was not returned and apparently was never used.
