Pam,
I haven't seen an answer to your post, so here are some answers.
I have used Karl-Heinz Steinbruch to perform research at the archives in
Schwerin. I found him to be very knowledgeable and helpful. Here is a link
to his web page:
You can email him by using the link on his page or by using:
Mecklenburgica.Steinbruch@t-online.de
The Family History Center mentioned would be the Family History Center at
your nearest Church of Jesus Christ of Latter-day Saints. In case you are
not aware of it, The Church has microfilmed a large volume of records from
Mecklenburg (including church parish records and several census). If you
knew the location of the birth, confirmation or marriage of your ancestor
you could go to their website at:
http://www.familysearch.org/eng/Library/FHLC/frameset_fhlc.asp
and perform a place search on their records to see if they have microfilmed
that church parish.
You can place a request at the local Family History Center to have the
microfilms sent to your local center so that you can view them (for a small
fee). If you were researching a rare surname you could possibly order the
1819 census index to find out what church parishes had that surname in 1819,
but with a name like Krueger that is not feasible. You would probably find
several hundred parishes with a Krueger.
If I remember correctly how this thread has gone, you do not know the
location, so you will probably need a researcher at the archive to at least
get you started. Without a village name it may be an impossible task for any
researcher, but if anyone can help you I think that Karl-Heinz can.
Hope that helps.
