My great grandfather, Johan Carl Meyer. was born October 13, 1838 in
Mecklenburg. In the 1880 census it says he was in Clayton Co., IA and
born in Germany. I do not find him in any census before 1880
so I would say between 1838 and 1880. We are at a loss on how to find
when he came.
Have you check the Hamburg Passengers list Index from 1872? There are a
lot of Meyers on that list. My family came from Mecklenburg also.this is
where I at last was able to find them.
