There is some variation on the spelling of Gernonstowne. On various maps and other documents it is spelled Gernonstowne, Gernonstown, Gernon's-Town, Gormanstown, Germanstown, Garlandstown, Garland, etc. Irish road signs show the English as Castlebellingham while the Irish translation still refers to "baile an Ghearlanaigh" - or Gernonstown. It was not called Castlebellingham for at least forty years after the purchase. The name does not appear on any document before the year 1700. About 1710 it began to appear in journals and other sources to be called Castlebellingham.
