Also note: “These were natives or natural-born citizens, as distinguished from aliens or foreigners.”
Hmmm...only two classes in that decision: “natives or natural-born citizens” and “aliens or foreigners” whose citizenship rested on naturalization.
Right.
At that time and even well after WKA, children born on American soil to foreign fathers were considered foreigners themselves. When the father was naturalized after five years, his children, those born here and those born abroad, became citizens. Until their father's naturalization, his wife and his children were aliens.
Check immigration history. The citizenship status of the father determined that of the wife and the children.
