Question: Is actress Rachael Stirling related to Patrick Macnee (The Avengers)? My friend thinks they look alike. — Alex, New York, N.Y.

Televisionary: Close — and it's an interesting guess, considering Ms. Stirling, a featured player on the BBC's Tipping the Velvet, is the daughter of Macnee's Avengers co-star, Diana Rigg. Her dad is Rigg's ex-husband, Scottish landowner Archibald Hugh Stirling.
