HARTMANN and SIMON in Novo Selo?

Hello! I am attempting to research my 3rd great grandparents, Johann Hartmann and his wife, Maria Simon who were apparently born in Novo Selo around 1843 and 1847, respectively. However, I am running into a brick wall. Would anyone be able to point me in the right direction for finding records for Novo Selo? I'd like to trace back further if possible. I do know that Johann and Maria also lived in Molidorf at a later time. 

Any help is greatly appreciated!
