Hello Jackie,
The Hannover emigration archives list these Seemann names:
PERS Seemann, Anton Dietrich Heinrich 13457
PERS Seemann, Chr. 13458
PERS Seemann, Dietrich Heinrich Christian 13460
PERS Seemann, Dorothee 13459
PERS Seemann, Dorothee Marie 13457
PERS Seemann, Friedrich Ernst 18882
PERS Seemann, Heinrich Conrad Friedrich August 13459
PERS Seemann, Heinrich Friedrich Christian Philipp 13457
PERS Seemann, Johann Heinrich 13459
PERS Seemann, Margarethe 13460
PERS Seemann, Philipp 13460
These are all shown (except for Friedrich) as coming from Neustadt/Rbg.
There are many German towns by the name of Neustadt, but I would guess that
this particular one refers to a town called Neustadt am Rübenberge. That is
located just northwest of the city of Hannover. The number code for each
one, except for Friedrich Ernst, point to the town of Neustadt/Rbg.
Friederich is from Wennigsen which is just to the southwest of the city of
Hannover.
You can order the records from the Hannover archives - they will give
you more information (birthdate, parents, occupation, etc) about them. They
are usually about $30 apiece. However, if you think this is some of your
family, you may decide just to pursue more information about them, knowing
that Neustadt is their place of origin. Of course, this is not a guarantee
that this is the right family.
By the way, the Hannover emigration records show this for Buchmeier:
PERS Buchmeier, Heinrich Christian 15316
PERS Buchmeier, Johann Friedrich Conrad 15317
They are from Springe, which is not far from Wennigsen, southwest of the
city of Hannover.
You might also look at the records on this website for the name Seemann:

There are many Seemann listed there in Ortsfamilienbuchs (and other
sources) which can be very helpful. It is unfortunate that the LDS do not
have the church records for Neustadt.
There are 6 listings in the German telephone book for Seemann in
Neustadt am Rübenberge today.
Good luck,
Barbara
