Richard, I hope you are still at this address. I have recently found through an 1843 U.S. Supreme Court case that I am descended from Solomon Isaacs who died in NY of yellow fever in 1793. His family tree starting with Solomon and Rebecca Isaacs who were in New York by the early 1690s is on p. 124 of First American Jewish Families by Malcolm Stern. You can find FAJF with all the family trees at
http://198.30.183.7/aja/FAJF. Is this your Solomon Isaacs family? We have communicated before when I thought I was descended from Isaiah Isaacs of Richmond. It turns out that Solomon Isaacs of New York married Mary ___ and after Solomon died his widow Mary married a Jacob King in Richmond and moved there. My ancestress Sarah Isaacs who married Benjamin Jewell in Richmond in 1813 in a Jewish ceremony was the daughter of Solomon Isaacs. Please contact me if this is the same Isaacs family.
