BBC programme 'Mixed Britannia'

This could be interesting and informative.

'Nearly 100 years ago, Chinese seaman Stanley Ah Foo arrived in Liverpool to start a new life. He soon fell in love - but laws at the time meant that his English bride, Emily, was only able to marry if she gave up her British nationality and became a so-called alien herself.
In Mixed Britannia - a new three-part series for BBC 2 - George Alagiah explores the often untold stories of Britain's mixed-race communities. He met Stanley and Emily Ah Foo's daughters, Doreen and Lynne, who told the remarkable story of how their parents met, and the restrictions placed upon them'
