  By using images taken with WFCAM on UKIRT and SofI on the NTT and combining
them with 2MASS we have measured proper motions for 126 L and T dwarfs in the
dwarf archive. Two of these L dwarfs appear to have M dwarf common proper
motion companions, and 2 also appear to be high velocity dwarfs, indicating
possible membership of the thick disc. We have also compared the motion of
these 126 objects to that of numerous moving groups, and have identified new
members of the Hyades, Ursa Major and Pleiades moving groups. These new
objects, as well as those identified in Jameson et al. (2008) have allowed us
to refine the L dwarf sequence for Ursa Major that was defined by Jameson et
al. (2008).
