Hello I have an ancestor named Johannes Dietlein b 1767 d March 1847 in Parish of St James, Dover. He must of came to England around 1800 and his name was later anglisized to Datlen.
First off is his surname likely to be German, Dutch or Austrian?
Secondly his first name is Hebrew in origin. Is it likely he was a Jew?
Lastly he came up in census returns as Adam Datlen with an "f" for foreign subject. How would I find his place of birth? Would I need to find a passenger list, if so from where?
