Demographics
Name origin and privateer past
The Island was owned in 1642 by James Neal, a privateer (a legal pirate working for the British Empire) who captured Spanish ships bearing treasure to Spain from Central America. Captured Spanish coins were cut into "cobbs" (smaller coins) and distributed to Maryland colonists, which led to the name "Cobb Island".
