I have a 3rd & 4th great grandfather who came to London in the early/mid 1800s, I've found more info on my 3rd GG than my 4th and I've found some death registers and found where they were buried (Stepney area) . I searched Deceased Online and found a document I can buy but will it give me much information such as where in Hamburg he was born? Ideally I'd like to find out more about their time in Germany. I've not found any passenger lists or anything that relates to their time in Germany. I've tried JewishGen but there isn't anything on there and found a marriage on Synagogue Scribes which was also on Ancestry. Apart from that I've only got bits and pieces that doesn't build too much of a picture.

Names are Vigidor (Victor) Lazarus And
