Using data samples of 102 million ϒ(1S) events and 158 million ϒ(2S) events collected by the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider, we search for [udscc[over ¯]] pentaquark states decaying to J/ψΛ. Using the first observations of ϒ(1S,2S) inclusive decays to J/ψΛ, we find evidence of the P_{cc[over ¯]s}(4459)^{0} state with a local significance of 3.3 standard deviations, including statistical and systematic uncertainties. We measure the mass and width of the P_{cc[over ¯]s}(4459)^{0} to be (4471.7±4.8±0.6)  MeV/c^{2} and (22±13±3)  MeV, respectively. The branching fractions for P_{cc[over ¯]s}(4459)^{0} production are measured to be B[ϒ(1S)→P_{cc[over ¯]s}(4459)^{0}/P[over ¯]_{cc[over ¯]s}(4459)^{0}+anything]=(3.5±2.0±0.2)×10^{-6} and B[ϒ(2S)→P_{cc[over ¯]s}(4459)^{0}/P[over ¯]_{cc[over ¯]s}(4459)^{0}+anything]=(2.9±1.7±0.4)×10^{-6}. The inclusive branching fractions of ϒ(1S,2S)→J/ψΛ/Λ[over ¯] are measured to be B[ϒ(1S)→J/ψΛ/Λ[over ¯]+anything]=(36.9±5.3±2.4)×10^{-6} and B[ϒ(2S)→J/ψΛ/Λ[over ¯]+anything]=(22.3±5.7±3.1)×10^{-6}. We measure the visible cross section σ(e^{+}e^{-}→J/ψΛ/Λ[over ¯]+anything)=(90±14±6)  fb for the continuum production at sqrt[s]=10.52  GeV. In all cases, the first uncertainties are statistical and the second are systematic.
