I know is many years later, but I think that the Bud you are referring to is H. M. Hilburn. I have a picture of him working in a mine and his driver license states H.M. Hilburn and Bud is in parenthesis. In my family papers there are also references and pictures of Sadoc, Tom and H. M. (Hyrem or Hirem, both spellings are wrong). They are all brothers. Tom is Thomas Jefferson my great great grandfather who was married to Mary Frances Holman Hilburn.
