"The first group of Jews to settle in North America were 23 refugees from Recife, Brazil. In 1654, they arrived at the docks of Dutch New Amsterdam on board a French privateer, the Saint Charles (sometimes dubbed the "Jewish Mayflower"). They were escaping persecution that resulted when Portugal reconquered Dutch Brazil in 1654. Most were descendants of Shephardic Jews, who had been expelled from Spain in 1492 and from Portugal in 1497. These first Jews who landed in Dutch New Amsterdam had little freedom. Initially, they were forbidden by law to own land or houses, worship in public, hold public office, vote, travel, stand guard, serve in the militia, or to enter trades and professions. -

Asser Levy and another Jewish settler, Jacob Barsimon, petitioned the new amsterdam council for the right to keep guard with the other burghers. although their original petition was denied, they appeared regularly with their muscats for military training and stood guard on the city walls. After two years the council finally relented and enrolled the men in the militia.
Their perservance planted the seeds of a tradition of Jewish American patriotism and service that has flourished throughout the history of the United States.

aish.com "Joachim Gaunse, a Jewish metallurgist and mining engineer from Prague, was invited to England by the Royal Mining Company in 1581. Britain, preparing for war with Spain, was desperately in need of copper. Copper was a critical element in the production of bronze, from which the English manufactured the accurate cannons that gave their warships an advantage over the cast iron cannons of the Spaniards.
"n 1584, in the hope of finding copper, silver and gold, Queen Elizabeth gave Sir Walter Raleigh a royal patent to explore the Virginia territory. Raleigh, then, asked Gaunse to serve as metallurgist and mining supervisor to the Roanoke expedition. Thus, in 1585, Gaunse became the first recorded Jew to set foot on English soil in North America." -
Judaism.about.comI found more references to 1654 than to 1585, but I suspect that the earlier date is factual. Actually, it may depend on how far north the Spanish got in (now) Mexico. If they crossed into (now) US territory, they may have had a Jew in their group.
