Jerome Bonaparte (1784-1860) was Napoleons youngest brother. He served in the navy and on a trip to the United States met Elizabeth Patterson and married her in 1803. However, since Jerome was a minor Napoleon didn't recognize the marriage. In 1807, Napoleon had his brother matched with Catherine of Württemberg and the two were married. Jerome became king of Westphalia from 1807- 1813 and fought in the Russian campaign.
