We have obtained high resolution optical and near-infrared spectra of suspected young brown dwarfs from the MIKE echelle spectrograph on Magellan, the NIRSPEC spectrograph on Keck, and the PHEONIX spectrograph on Gemini-South. In this poster we present radial velocities and combine them with distances and proper motion to determine their true UVW stellar velocities, assign cluster membership, and adopt ages. If the brown dwarf stars are indeed young and cluster members as we suspect, they will be benchmark stars to calibrate other observable youth indicators among brown dwarfs.
