I can't believe we're still hearing this stupidity.
Actually Thom, Jefferson was the first president with one foreign born parent. BOTH of Andrew Jackson's parents were Irish immigrants:
Andrew Jackson (1829-1837) is the only president born of two immigrants, both Irish. Presidents with one immigrant parent are Thomas Jefferson (1801-1809), whose mother was born in England, James Buchanan (1857-1861) and Chester Arthur (1881-1885), both of whom had Irish fathers, and Woodrow Wilson (1913-1921) and Herbert Hoover (1929-1933), whose mothers were born respectively in England and Canada.
