  We propose a first model of quarks based on the discrete family symmetry
Delta (6N^2) in which the Cabibbo angle is correctly determined by a residual
Z_2 times Z_2 subgroup, and the smaller quark mixing angles may be
qualitatively understood from the model. The present model of quarks may be
regarded as a first step towards formulating a complete model of quarks and
leptons based on Delta (6N^2), in which the lepton mixing matrix is fully
determined by a Klein subgroup. For example, the choice N=28 provides an
accurate determination of both the reactor angle and the Cabibbo angle.
