See Wong Kim Ark. It was 23 years later than Happersett, and answered the question about children born here of alien parentage. Happersett did not answer that question.
WKA mentioned Citizen but not Natural Born Citizen. WKA said the parents had to be here with legal residency for Wong to be a Citizen, not natural born Citizen as mentioned in Article 2 Section 1. Nikki Haley’s parents had not established legal permanent residency in the states when she was born. Same with Kamala Harris and Jindal. They are not natural born Citizens.
