Freda. It was me who originally suggested - very tentatively - Lord Bernard Montgomery. As far as I remember the actual clue was 'Complete man of the house', to which the answer might be (the ) full monty.
Translating that into a famous person, the best I could come up with was Lord Bernard Montgomery. ( The words fitted the letter pattern 4, 7, 10)
Field Marshal the Viscount Montgomery of Alamein was nicknamed Monty: he might have been known as Lord Montgomery informally, or as Bernard Montgomery by his friends and relations , but he would never have been called Lord Bernard Montgomery.
I would love to see a better suggestion!
