Word has come down that on my mother's side (Chandler) Mary Dan, b. 1741, Norwich, England, was Sephardic. Is this possible? Mary Dan moved to Greenock, England where she married great grandfather Chandler. They immigrated to Lynn, MA, where they and other Chandler brothers operated a shoe factory. If there is a basis to this family story, how do I find out more about the Dans? Thanks so much for any information.
