Zoller_Lahres_Munig of Rollfeld, Bavaria

I am looking for information on any of the families: Zoller, Lahres or Munig. I know the Zollers and the Lahres were from Rollfeld, Baviaria having emigrated to New York city between 1857 and 1866. Sophia Zoller married Franz Munig in NYC in 1867. Alois Lahres married Anna Zoller in NYC in 1867, and Dominick Lahres married Margaretha Kehl in NYC in 1858. Sophia's parents were Lorenz and Elizabetha. The parents of Dominick and Alois were Gabriel Lahres and Catharina Zoller.

The only information I have on Franz Munig is that he was from Pulan, Bavaria, which I have been unable to find but suspect it may be near Rollfeld.

If anyone has any information or suggestions to pursue, I would be very appreciative.
