The Marlborough moniker given to the soap above by D.R. Harris alludes to a
dukedom and the very same noble house from which Winston Churchill was descended (google «Duke of Marlborough» and «Blenheim Palace» — the latter being only one of a couple non-royal estates in England to be called a palace and a mansion I'm sure
most gents will say they've seen in film or on television more than once!).
