I found this on the web, it explains why so many Germans emigrated around the 1850s
"Farmhands, daylaborers and servants from the part of Hannover known as Nasses Dreieck or Elbe-Weser-Dreieck migrated from the Kingdom of Hannover in hopes of better employment to London, England. Here in the East End of London was a thriving sugar refinery industry which employed 1.200 workers (before 1850) of which 1000 were Germans from the Elbe-Weser region.
The workers of the sugar refineries were predominantly single men who were looking for better earnings and in some cases, dodged the draft. For some it was indeed possible to save up money, return home, marry and establish themselves by paying off debts. Some even managed to become self-employed or move on to settle in the United States.
It was feasible for these men to establish themselves in London, because those who had gone before, would help them with employment and housing. There were churches and inns where a German could feel at home without really having to adopt to the local culture. Those men who decided to marry and settle in England also found German schools, hospitals and clubs to attend. Even a fire insurance company was established in their behalf which still exists today."
