I was born abroad to a British citizen, and I am considered a British citizen myself, although I have not at any time permanently resided in that country.
It stops at one generation, though. My children are not British citizens and cannot easily become so unless they reside in the UK for at least three years before turning 18.

It is my understanding that this manifestation of Jus Sanguinus law was enacted by Parliament sometime back in the 1500s. It isn't part of "Common Law" but is instead an application of positive law.
