The JRI-Poland record for his son Loebel's birth notes that the father had died on 08.10.1834.

All his children were born in Langendorf and Loebel died there. It is tempting to speculate that he was therefore a son of Joel Loebel Cohn, the first Cohn in Langendorf; however Joel's wife Charlotte (who was still married to Joel when she died in 1827) would have been aged around 50 years at his birth, which is unlikely.
