“It is an established maxim, received by all political writers that every person owes a natural allegiance to the government of that country in which he is born. Allegiance is defined to be a tie, that binds the subject to the state, and in consequence of his obedience, he is entitled to protection… The children of aliens, born in this state, are considered as natural born subjects, and have the same rights with the rest of the citizens.”
Zephaniah Swift, A system of the laws of the state of Connecticut: in six books, Volumes 1-2 of A System of the Laws of the State of Connecticut: pg. 163,167 (1795)
