  We present visible spectroscopic and albedo data of the 2.3 Gyr old Themis
family and the <10 Myr old Beagle sub-family. The slope and albedo variations
between these two families indicate C-complex asteroids become redder and
darker in response to space weathering. Our observations of Themis family
members confirm previously observed trends where phyllosilicate absorption
features are less common among small diameter objects. Similar trends in the
albedos of large (> 15 km) and small (< 15 km) Themis members suggest these
phyllosilicate feature and albedo trends result from regolith variations as a
function of diameter. Observations of the Beagle asteroids show a small, but
notable fraction of members with phyllosilicate features. The presence of
phyllosilicates and the dynamical association of the main-belt comet
133P/Elst-Pizarro with the Beagle family imply the Beagle parent body was a
heterogenous mixture of ice and aqueously altered minerals.
