I have catalogued over 300 names related to the decendents of Hans Knorr born in Germany in 1570. The tree expands greatly in 1725 when the Knorrs arrived in Philadelphia. I am most interested in expanding the details of the Knorr familiy in the period of 1570-1725. Some key names during this period are Hans, Johannes, George, and Johan all based in Germany. I am preparing this information as part of afamiliy year 2000 gift. I would greatly appreciate any assistance you may be able to provide and would of course be happy to share with you any information that I can provide.
