Our earliest direct ancestor so far is Raphael Kahn, born in Schweich, Germany in 1725 +/- 5 years. In 1747 he married Brendel Joseph Levy (born Schweich about 1725).
They had five children: Nathan Kahn (1745); Schielen (1747); Esther (1748); Feist (1749); Bernahardina (unknown birth). They all lived in Schweich.
