The description doesn't match the poll options. Or perhaps the term "first person" is ambiguous. I think you mean the "last" person, as in most recent right? As in looking for the smallest number of generations back before one ancestor immigrated. It seems by the comments people are focusing more on the the "chronologically first known" immigrant in their family trees. I answered 0, but in my known family tree the first (as in least recent) immigration occurred around 30 generations ago, (have to dig out the papers to get the exact number). I suggest rewording it so instead of "first" you say "most recent" or "least recent" depending on what you actually mean.
