I have come to understand that my immigrant ancestor, John(Johann?) Christian Kuntz immigrated to America through the port of New Orleans between 1851 and march 1852. The passenger list indexes for this port available online do not include this time period, except for a few months in 1851.
Am I correct in believing that even though the indexes for this period are not available online, there are still ship manifests stored at the State Archives for this period?
If that correct, could someone point me to a researcher, group or agency, that would be capable of searching the archives for my ancestor? I am not asking for a freebie, I just need some direction.
