I think you're right about the Queen Mother -- another decent English girl taken in by that 'German lot'. (Perhaps I am prejudiced slightly as the descendent not only of six veterans of the War for Independence, but (illegitimately) of John Lackland and (legitimately) of two of the barons who stood surety for Magna Charta)
Ahem. Actually a decent Scottish girl. She was a daughter of the Earl of Strathmore ( which sounds like it should be a good malt whiskey) a Scots earl. The family was famous for its longevity even before she hit a hundred.
