I am very glad to get the information about Bernard Knorr's children and would like to get any additional information about him or from his estate papers. The only reference I have is that they are filed under Philadelphia Administration #1:1817. I am descended from Catharine Knorr who married John Castor. She was born April 14, 1779 and died in September 1824. Her sister Mary married Henry Castor, John's brother, as his third wife. Do you happen to have come across Bernard Knorr's wife's maiden name? The only clue I have is that Catharine named her second daughter "Hannah D."
