Using data collected in the region of the Upsilon(4S) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring (CESR), we present the first observation of B mesons decaying into the charmed strange baryons Xi(c)(0) and Xi(c)(+). We find 79 +/- 27 Xi(c)(0) and 125 +/- 28 Xi(c)(+) candidates from B decays, leading to product branching fractions of B((B) over bar --> Xi(c)(0)X)B(Xi(c)(0) --> Xi(-)pi(+)) = (0.144 +/- 0.048 +/- 0.021) X 10(-3) and B((B) over bar --> Xi(c)(+)X)B(Xi(C)(+) --> Xi(-)pi(+)pi(+)) = (0.453 +/- 0.096(+0.085)(-0.065)) X 10(-3).
