I found it accidently the way best things are found.

It is all the ship lists for 1869. You can work with the arrival date.
Search here and then go back to the Hamburg list from germany and see
if all the same. Maybe two to three weeks back.
While going through passenger lists I happen to see a Luhmann from
Eichdorf traveling to amerika. I left it and hurried on. Later, I
looked one up at castle garden. Yes may 5,1869. Then I found I did
find this Luhmann on hamburg lists leaving
april 16, 1869 with his wife and daughter. Finding this information
of above short cut is wonderful. Very nice to know. Not sure if it is
the same as posted before.
Now have to go back and find him on german list to make sure there
were not two different sets. Something is nagging at me that I
thought the mans name was Christian or Ernest and this Luhmann is
listed as Heinrich only. I know I wrote down the page number of the
first Luhmann I saw SOMEWHERE.
Now an added subject AIRLINES are also included, if there were any
in 1869. But it suggests data to 1950's.
It could be helpful.
