Both North Carolina and South Carolina claim that Andrew Jackson was a native son. Jackson's birth certificate was elusive, just like that of the Hawaii born Kenyan.
I first read about Jackson's alleged birth at sea in The Frontiersman by Allen Eckert. It's the story of Simon Kenton who had an encounter with Andrew Jackson as a young man. The encounter was recorded. Check it out:
"But historian and novelist Allen W. Eckert claims in a footnote in his book, The Frontiersman, to have uncovered evidence that Jackson was actually born on a ship at sea in 1755. The evidence comes in the form of a story about a bar fight between Jackson and the book’s protagonist, Simon Kenton, that Kenton recounted in interviews later in his life. According to Kenton, he and Jackson, whom he did not know at the time, were about the same age. There is also, according to Eckert, a secondhand account of a remark by Jackson who responded to a question from a man named Marshall Anderson about his place of birth with the answer, 'I was born at sea.'"
