This document is page 1334 of the 1903 Register, Volume 2, for Rural Free Delivery - Tennessee showing an entry for Cullen Millington Hungerford (LM412 in the Surnames Database). The document establishes Cullen's middle name as Millington and discloses his compensation at $600.
This document conflicts with the entry for him in the the 1905 Register with respect to the place of his birth. This entry states that he was born in Tennessee (incorrectly) whereas that entry states that he was born in Louisiana (correctly).
