I am descended from Barburah Suesanger and Nicholas Susong who both fought in the American Revolution. They were married and had a son Andrew. He as well fought in the Revolution.
They were on a secret ship sailing from Spain (during the war) with the Marquis de Lafayette, but originated from Alsace-Lorraine, France. I think they were Sephardic Jews by blood. Please let me know if you have any information on the family. Susong is not a common name in the US.
