It is difficult to get numbers on the number of Muslims in the colonies around the time of the Revolution since some were taken as slaves from Africa and their religion was not acknowledged. Of about 3.5 million free persons and about 0.5 million slaves in the colonies around 1776, there were only about 3,500 Jews mainly in Philadelphia, New York, Savannah and Charleston. There were about 125 that served in the Continental Army, a high percentage relative to other religious or ethnic groups (reference
Angel in the Whirlwind: The Triumph of the American Revolution by Benson Bobrick).
Very few Jews were Loyalists. In some colonies, they were prevented from holding office since they were not Christian, but that is not to say that they were not treated fairly during colonial times.
Aside from their service in the army, Haym Solomon played a role in raising money to pay the troops, government functionaries as well as congressmen (and even loaned money to James Madison).
As you likely know, Maryland was a Catholic colony and if it were not for that and the wealthy and well respected Carrolls, there would have been no Catholic Signers.
Haym Salomon might not have signed the Declaration of Independence, but he was indispensable to it. Without him and Robert Morris (another Pennsylvania boy, by the way), we could never have financed the revolution. Both died impoverished, Salomon the much worse off especially for his generous help to the cause.
Think about that the next time you slight Jews.
