Its a pity your SNP supporter friend(s) failed to mention the Marquis of Bute, Robert.
The 2nd Marquis of Bute funded Charles Cameron's book - 'The Baths of Ancient Rome'. It was through its publication that Cameron was brought to the awareness of Catherine the Great. Many believe that Cameron's redesign of the Catherine Palace interiors is creatively and artistically the finest in the ensemble. Cameron also designed that most exquisite of buildings - The Grand Palace, Pavlovsk.
Johnnie Dumfries - the 7th Marquis of Bute - is a young(ish) well-liked man whose stately pile - Mount Stuart - on the Island of Bute, is worthy of a 'google.... and it was the venue for Stella McCartney's wedding.
However, apart from the segway above, I have to say 'what's in a name?'

I'm very familiar with the Marquesses of Bute. They are descended from William IV directly through his daughter Elizabeth, Countess of Erroll. They have the most amazing Gothic Mansion, a Palace I suppose it is. Each Marquess has been rather notable, including the present, but the Third Marquess, well when reading about him I was amazed by his accomplishments, and the 3rd Earl of Bute was the Prime Minister of course and was a great friend and mentor of George III, before they parted ways, however he remained very close always to the Dowager Princess of Wales - Augusta. It seems some of the most well-known Marquesses start with B- Bath, Bristol, Bute.
Anyway, before all this, I was originally trying to suggest that it would have been good for Prince Edward to have been made a Marquess while he waits to become a Duke, but as he apparently wanted just to be created an Earl, then it's fine.
I agree with the comments about Sophie - I think she is becoming more beautiful and attractive as time goes on, getting older has only improved her, or perhaps it is motherhood as well.
