There are more than a few historic Featherstone buildings in the United Kingdom.

The Castle, home of the Fetherstonehaugh's way back in the past, thought by many researchers to be the place where the name first appeared. Early records give us Elias or Helius in 1210. Located in Northumberland near Haltwhistle is now in private hands and is used as a youth centre for church groups.
