Census look up or any information on this family or any Hempen family in Hannover would be appreciated

Dear Jens: Thank you very much for trying to find something on this family.
Unfortunately all I know is from an 1880 US Federal Census that listed
Hanover as the birthplace (with that spelling not Hannover) and nothing
else. I also don't know as yet when this family came to the US and if they
came straight to Missouri or stopped off earlier in another state. So, I
can't see asking a researcher to look for them at this time. However, I
will keep the information and when I find out more, I will contact you in
the future.

Thank you again for this very generous offer you made to the list and for
trying to find my family.

If you ever need anything looked up here in St. Louis, Missouri please feel
free to contact me. We have 2 very good libraries with genealogy
departments here in the City and County as well as a very active Germans to
St. Louis e-mail list. I would be happy to do a look up here for you.

Laura Bozzay (wife of Ron and the Hempens are really my side of the family)
Thanks again!
