  We present a study of baryon ground states and low lying excitations of
non-strange and strange baryons. The results are based on seven gauge field
ensembles with two dynamical light Chirally Improved (CI) quarks corresponding
to pion masses between 255 and 596 MeV and a strange valence quark with mass
fixed by the Omega baryon. The lattice spacing varies between 0.1324 and 0.1398
fm. Given in lattice units, the bulk of our results are for size 16^3\times 32,
for two ensembles with light pion masses (255 and 330 MeV) we also use
24^3\times 48 lattices and perform an infinite volume extrapolation. We derive
energy levels for the spin 1/2 and 3/2 channels for both parities. In general,
our results in the infinite volume limit compare well with experiment. We
analyze the flavor symmetry content by identifying the singlet/octet/decuplet
contributions of the resulting eigenstates. The ground states compositions
agree with quark model expectations. In some cases the excited states, however,
disagree and we discuss possible reasons.
