Nathaniel (or Nate) was formerly a resident of Boston that moved with his family in Kansas, Smallville
back in the mid 1850's and took up the job of a Sheriff.
With the recent events that took place in Superboy
(Vol. 4), it was revealed by Phantom Stranger
under the disguise of a Smallville resident that, in 1871, Nate along with deputy Albert Valentine were doing their best to keep the peace alive in Smallville until Eben Took
and his family started getting involved in Necromancy and Witchcraft which lead -decades later- to the "Hollow Men" events.
