  Using the F-theory realization, we identify a subclass of 6d (1,0) SCFTs
whose compactification on a Riemann surface leads to N = 1 4d SCFTs where the
moduli space of the Riemann surface is part of the moduli space of the theory.
In particular we argue that for a special case of these theories (dual to M5
branes probing ADE singularities), we obtain 4d N = 1 theories whose space of
marginal deformations is given by the moduli space of flat ADE connections on a
Riemann surface.
