Using data recorded by the CLEO III detector at the Cornell electron storage ring (CESR), we have made measurements of some properties of the Sigma(c)(*)(++) and Sigma(c)(*)(0) charmed baryons. In particular: Gamma(Sigma(c)(*)(++)) = 14.4-1.5+1.6 +/- 1.4 MeV, M(Sigma(c)(*)(++)) - M(Lambda(c)(+)) = 231.5 +/- 0.4 +/- 0.3 MeV, Gamma(Sigma(c)(*0)) = 16.6-1.7+1.9 +/- 1.4 MeV, M(Sigma(c)(*0)) - M(Lambda(c)(+)) = 231.4 +/- 0.5 +/- 0.3 MeV.
