Good morning! I'm still looking for any possible clues to when and why my 14-year-old great-great grandfather emmigrated from Germany with his 12-year-old brother. Would it be possible for someone to give me a bit of background on the German emmigration between 1840 to 1850? Hopefully, that might give me some clues. I have WATERHOLTER information from 1850 onward, but not much data before 1850. Thanks! Pat McCoy
