The first American born President spoke English as a second language!
Martin van Buren was our 8th President and the first one to be born as an American citizen. He was also the first President not born of English or Irish descent. His family was Dutch.
Van Buren was born in Kinderhook, New York and grew up in a Dutch community. The entire community spoke Dutch. He is the only President to have spoken English as a second language.
Van Buren married his childhood sweetheart and first cousin once removed, Hannah Hoes. They had 5 sons and 1 daughter together. Hannah grew up in Kinderhook, as well, and never lost her Dutch accent. Van Buren became a lawyer and served as the 10th Secretary of State and the 8th Vice President.
