Young, low-mass stars in the solar neighborhood are vital for completing themass function for nearby, young coeval groups, establishing a more completecensus for evolutionary studies, and providing targets for direct-imagingexoplanet and/or disk studies. We present properties derived fromhigh-resolution optical spectra for 336 candidate young nearby, low-mass stars.These include measurements of radial velocities and age diagnostics such asH$\alpha$ and Li $\lambda$6707 equivalent widths. Combining our radialvelocities with astrometry from Gaia DR2, we provide full 3D kinematics for theentire sample. We combine the measured spectroscopic youth information withadditional age diagnostics (e.g., X-ray and UV fluxes, CMD positions) andkinematics to evaluate potential membership in nearby, young moving groups andassociations. We identify 78 objects in our sample as bonafide members of 10different moving groups, 15 of which are completely new members or have hadtheir group membership reassigned. We also reject 44 previously proposedcandidate moving group members. Furthermore, we have newly identified orconfirmed the youth of numerous additional stars that do not belong to anycurrently known group, and find 69 co-moving systems using Gaia DR2 astrometry.We also find evidence that the Carina association is younger than previouslythought, with an age similar to the $\beta$ Pictoris moving group ($\sim$22Myr).
