Built and maintained by Harry Stein from 1999 to 2013. His names engine indexed more than sixty books, and the research guides that still link here link because of his work. He died on 8 August 2015. The site continues at the same address, and his original section URLs still resolve.
Nothing here is a substitute for a document. A surname is a lead; a named person in a dated record is evidence.
