Goans in Swindon, Southall, Wembley

These towns in the UK are generally famous for having a large number of Goans.
Out of curiosity, what Goan villages do these Goans come from? Is it one specific village of Goa or well distributed between Bardez, Tiswadi and Salcete?

For example in Canada and Australia, Goans usually didn’t come straight from Goa, but from East Africa, Karachi, Dubai or Bombay, and generally are originally from Bardez.
