I know that the Geisz surname is a German name (Geis,Geist, Geiss, Geisse, etc...) with a hngarian plural (z). I think that my great grandfather Mathias Geisz came from the Banat region but am at a brick wall with this person. if anyone has any information on Mathias or the etymology of the Geisz name I would be very appreciative.
Thanks
