We present our initial study of the electromagnetic splittings of charged and neutral mesons, and the violation of Dashen's theorem. Hadron masses are calculated on MILC Nf = 2 + 1 QCD ensembles at lattice spacing ≈ 0.15 fm, together with quenched non-compact U (1) configurations. The O (a2) tadpole improved staggered quark (asqtad) action is used both for the sea quarks and for six different valence quark masses. Chiral extrapolations are performed using partially quenched chiral perturbation theory incorporating electromagnetic corrections.
