In this work we combine information from solar-like oscillations,high-resolution spectroscopy and Gaia astrometry to derive stellar ages,chemical abundances and kinematics for a group of seven metal-poor Red Giantsand characterise them in a multidimensional chrono-chemo-dynamical space.Chemical abundance ratios were derived through classical spectroscopic analysisemploying 1D LTE atmospheres on Keck/HIRES spectra. Stellar ages, masses andradii were calculated with grid-based modelling, taking advantage ofavailability of asteroseismic information from Kepler. The dynamical propertieswere determined with Galpy using Gaia EDR3 astrometric solutions. Our resultssuggest that underestimated parallax errors make the effect of Gaia parallaxesmore important than different choices of model grid or -- in the case of starsascending the RGB -- mass-loss prescription. Two of the stars in this study areidentified as potentially evolved halo blue stragglers. Four objects are likelymembers of the accreted Milky Way halo, and their possible relationship withknown accretion events is discussed.
