That again is a technicality. They were not indigenous, they were a different religion, many were not primarily English-speaking. None of that is true of people from Yorkshire (apart from the English speaking part perhaps). Their presence here didn't go down well and they faced a great deal of prejudice. They changed the character of parts of London and other cities and gravitated heavily towards manual work and the construction industry. Sounds familiar doesn't it...?
Lets not forget that London, in the main, is quite a dreadful place.
