We present preliminary results of a search for previously unidentifed stellar associations in the second data release (DR2) from the European Space Agency's Gaia satellite. Gaia DR2 contains precise astrometric data on more than 1.2 billion stars in the Milky Way Galaxy. We have modifed a Python code originally intended to identify wide stellar binaries through a Bayesian formulation, which includes correlated uncertainties in the proper motions and parallaxes, to expand it to larger stellar
