From Vemmedrup, Bjæverskov to Christianhavn Kvarter Prison

[Kari Andersen]

I am trying to find information on Jens Frederik Pedersen, son of Peder Holm Bruun and Marthe Marie Egberg, born in Vemmedrup, Bjæverskov, 10 November 1827.  According to 1850 census he was krigtjeneste and tjenestekarl in Gørslev By.  In the 1860 census he is forbedringshusfange at Christianhavn Kvarter on Baadmandstræde.  I assume Jens Frederik Pedersen was a prisoner. If so, can anyone tell me where I can find more information i.e. why he became a prisoner? My second question relates to the 1850 census where Jens Frederik is krigtjeneste. Where can I find the military roll? Could he have fought in the Schleswig-Holstein war?

Thanks

Kari
