We systematically study and obtain the large-volume analogues of fractionaltwo-branes on resolutions of orbifolds C^3/Z_n. We study a generalisation ofthe McKay correspondence proposed in hep-th/0504164 called the quantum McKaycorrespondence by constructing duals to the fractional two-branes. Details areexplicitly worked out for two examples -- the crepant resolutions of C^3/Z_3and C^3/Z_5.Comment: 34 pages, 2 figures, LaTeX (JHEP3 style); (v2) typos corrected; (v3) sec 3 reorganise
