Charles Grafton from Oldenburg, B 1827

I am looking for any information about my Great-Grandfather, Charles
Grafton, born in Oldenburg 19 May 1827.
We believe he immigrated to the USA in about 1846. He lived in Ohio,
then Kentucky and finally in Alabama.

I will live in Germany for the next year or two, and plan to travel to
Oldenburg in pursuit of information.

I would greatly appreciate any information, advice, or contact
information for a possible visit.

Hello Terry,
you are sure that GRAFTON is the right spelling?
The german phone directory listed only one Grafton address in Hamburg, far away from Oldenburg.
Was he lutheran or catholic?
