Hi Monica, I'm not sure if I have contacted you before, but I'm just sorting out all my bookmarked sites (this is one of them!)
My branch of the Zoller family from Dorph. changed their name to 'Sellers'(my mum's line). Michael John Zoller, also known as Franz Michael and John,(1805-1860) married Mary Ann Crips/Krebs/Keeps (1807-?)in 1833 and came to Australia in 1854. Michael was a stonemason who died in Sydney. His parents in Bavaria were Martin Zoller (also a stonemason) and Elizabeth -? I'd love to know more about the Bavarian side.
