Nthgenimmigrant

I find it funny how the ancestry logic (presumably European) sounds so alien to US ears. Our majority isn't 30th-generation immigrants.

But what claim does ancestry truly offer? If my parents are from the UK, do I qualify for Super Citizenship there? What if those parents had only been UK citizens for 2 generations? What if it's my great-grandparents, but they were part of a lineage that spent 22 generations "building" the UK, surely an absence of only 3 generations is just a rounding error!
