We learn that Coanwood was "anciently written" as "Collingwood", meaning "hazel trees / wood". Brings to mind (though it would seem, no direct link between the settlement and the gentleman concerned), Admiral Cuthbert Collingwood, First Baron Collingwood (1748 -- 1810): a Northumbrian, and by all accounts a thoroughly "good egg", concerned re humane and just treatment of the ordinary R.N. sailor. When not at sea, the Admiral lived at Morpeth, Northumberland -- was wont to go walking in the neighbouring hills, bringing with him a pocketful of acorns: which he planted at suitable spots, with view to helping there to be, far into the future, a continuing supply of oak trees for the construction of warships.
