The Royal Photographic Society has helped actress Alex Kingston learn more about her great-grandfather and discussed her photographic history for BBC1's Who Do You Think You Are? television programme. Kingston is best known for her roles in ER and Dr Who. 

The Society's Director-General Michael Pritchard filmed part of the programme in the stores of the National Media Museum, Bradford, with Alex earlier this year and looked at her ancestor William Keevil, who died during the First World War, leaving behind a wife and young family - including Alex's then 4-year-old grandmother.

Alex set out to investigate exactly what happened to William, and discovers how his pre-war career as a photographer put him in an unusual position.
