Good guess, Ann. Martin Van Buren was the only president who didn't speak English as a first language even though he was born in New York. He was indeed of Dutch ancestry and spoke Dutch.
He was Jackson's vice president and was one of the main founders of the Democratic Party.
As a bit of trivia, Van Buren was the first president who was born a citizen of the United States whereas all the previous presidents were born English citizens.
He was also president during the incident with the Amistad, a famous ship where slaves rebelled and were captured by the US Navy. If I remember correctly, the incident was made into a Hollywood movie.
