Well-known
Patrick Lichfield (the Earl of Lichfield) was the Queen's cousin. He's busy decomposing.
Tony Armstrong-Jones shagged Princess Margaret. Since she couldn't marry a commoner he was made the Earl of Snowdon. He's still clicking.
The natural-born toff was a far nicer person, by all accounts.
Both were nice enough blokes actually. Snowdon used to live just round the corner from me (he may still do) and I would regularly see him when I took my dog for its evening 'constitutional'. He would always say hello. Last few times I saw him he was on crutches or in a wheelchair as the result of his childhood Polio which had come back to haunt him.
But I believe it was Snowdon who introduced the Queen to Leica cameras.
