I noticed that Alex Kingston has been in a few episodes of the 2009 series of Law and Order: Special Victims Unit playing a lawyer.

Her character is called Miranda Pond.

Now that same unusual surname turns up in Doctor Who in an episode alongside Alex Kingston.

Just a coincidence, I presume.

I think you presume correctly

I thought it was an unusual name but maybe not, the Lib Dem candidate in Norwich North was also called Pond (April) http://news.bbc.co.uk/1/hi/uk_politics/8167922.stm

That's very weird as Alex has since played Amy Pond's daughter Melody Pond in Series 6 of DW.

According to the definitive resource for data on surnames in the UK, 'sofeminine.co.uk' (?!?), Pond is the 1,211th most common surname, equal with Crabb, Harley and Prevost. For a comparison, Tyler is 549th and Oswald is 6,540th.

HAS SHE???????
