I will present preliminary results from two followup projects based on the Martell & Grebel (2010) discovery of halo field giants that appear to have formed in globular clusters. Abundances from high-resolution spectroscopy appear to confirm the stars' in-cluster origin, and more followup spectra are being taken. We are also conducting an analogous search for CN-strong giants in the SEGUE-II data set to explore possible differences in the origins of the inner and outer halo.
