…Jerome Bonaparte, brother of Napoleon, and his wife Elizabeth “Betsy” Patterson of Baltimore were separated when Betsy sailed to France. Denied entrance by Napoleon, she had her child in England.
That son, Charles Joseph Bonaparte, in 1905 became the Secretary of Navy for the United States under President Roosevelt. In 1906, Charles became the US Attorney General. He organized a group of Agents that would evolve into the FBI as we know it today.
