Chester Curtis was born in 1860 and his father fought for the Union during the War Between the States — what country are you saying his father was a citizen of in 1860?
Fair Question: Here's your answer. He was born in Kansas prior to it becoming a state, on an indian reservation. At the time, the supreme court had ruled that indians were not citizens (check out Elk v. Wilkins).
Calhoun is more tenative surrounding the immigrant status of the father.
Arthur was elected as a vice president, and gained the presidency after garfields assasination. His father was naturalized in 1843 - Arthur was born in 1829.
All three were controversies in their times of varying levels.
All three instances were found by googling "Natural Born Citizen" and "Vice President".
Have a great evening.
Which Indian reservation, exactly, do you contend Curtis was born on? Do you have a cite? Every reference I find says he was born on a farm in Eugene, Kansas, now part of North Topeka.
I will take your comment on Calhoun as a retraction of your fallacious claim.
I didn’t ask about Arthur; because that has been well hashed-out here. Arthur was an illegitimate President who burned all his papers and hid his father’s naturalization status.
