Hi Shirley!
There is the Mecklenburg-Schwerin Census of the year 1819, which I'm transkribing with other researchers. You can find the results ( uptill now about 20 000 persons of 3 000 000)under:
www.akvz.de
On the left side of this page there is "Datenbanksuche". Click on this button and a new screen opens.
Input the name "Keyser"(Keiser or similar)under "familienname" and click "suchen". You'll get results of all published censuses (Mecklenbug-Schwerin and Schleswig-Holstein). In the case "Keyser" with positive results!! You can reduce the search, if you enter the year of the census in the roll down window (is that the right word?)
Good luck!
Marion Winter (Australia) is searching for KEYSER, too. marion.winter.art@bigpond.com
Had recently contact to her.

But there is hope in a hopeless world!
