Now that's a name to conjure with

That would be Helen Mirren, born Ilyena Lydia Vasilievna Mironov in 1945, which makes her (after the late Sophia Loren) one of the most delectable 65-year-olds around, even if she is married (to Taylor Hackford, the famous director).
Her grandfather, Piotr Vasilievich Mironoff, was a Tsarist (White Russian) aristocrat who was in London in 1917, negotiating an arms deal for the Tsar, when the Russian Revolution stranded him there. His wife and son (Helen's father) eventually joined him in London.
She was awarded the Dame Commander of the Order of the British Empire in the 2003 Queen's Birthday Honours List for her services to drama. (She allegedly refused the C.B.E. (Commander of Order of the British Empire) in 1996.)
Despite her Russian birthname and ancestry, she does not speak Russian. Her great-great-great-great-grandfather was field-marshal Kamensky, one of the Russian heroes of the Napoleonic wars.
She is the only actress to play both Queen Elizabeth I (in Elizabeth I, in 2005) and Queen Elizabeth II (in The Queen, in 2006).
She is fluent in French, and owns houses in Los Angeles, London, and the south of France.

"I don't mind being sexy, but on my terms. To this day, I love sexuality. I love the art of sexuality. The mysterious, the artistic, and the slightly perverse. I'm interested in all that."
"I try not to think of my own mortality but, as I get older, it gets darker, there is no question about that. You just say: 'It's going to happen and it's going to happen to everybody'."
