Another something-of-obsession of mine: J.R.R. Tolkien. The "Barnham" part of Barnham Broom, means by one reckoning, "Beorn's homestead / village" (the "Broom" bit, a very much later addition): thoughts conjured up, of Beorn the redoubtable shapeshifting man / bear in The Hobbit, and his homestead, where the travellers stay for a while. Another imaginable association re Tolkien's fiction: Rivenhall, Essex (near Witham) -- shades of, in The Lord of the Rings: Rivendell, Elrond's stronghold and place of great beauty.
