  We consider several neutrino mass models in an extra-dimensional setting on a
quantitative level. All the models are set in a five-dimensional scenario, with
the standard model (SM) particles living on a brane, while three additional SM
gauge singlets live in the bulk of an extra dimension, which is compactified on
a S^1/Z_2 orbifold. The spontaneous breaking of an additional, continuous U(1)
family symmetry is used to generate suitable neutrino mass matrices via single
right-handed neutrino dominance through the corresponding five-dimensional
extension of the see-saw mechanism. In this manner possible problems of this
combination for some models in four dimensions could be overcome. The
considered models differ with respect to the charges under the family symmetry
and the nature of the five-dimensional Majorana mass term.
