I was researching some family who came over from Hungary. The last name Czimbek appears to be of a string of family listed in one passenger list. It was an entire family and further searches yield no results. This family would have been Jewish. I was wondering if there is a database of common names changed upon either arrival or departure in certain times and via certain areas. I.e. I know the names "Cohen" and "Levy" are frequently used to re-name families whose own names were indeterminate depending on the location they were born in (or so I was told...). Any links to a database would be great. Thanks!
