We present the current status of our search for new galactic gamma-ray binaries and microquasar systems based on a cross-identification algorithm using public archives and databases. In particular, we report about the case of the emission-line star VES 737 located nearly two degrees above the galactic equator. This object is a star with a B9V spectral type interestingly consistent with the X-ray source 2E 0216.9+6248, and the gamma-ray sources EGRc J0225+6240 and 2FGL J0221.4+6257c. The possibility of association between the star and the high energy sources is assessed, and observations with the Karl G. Jansky Very Large Array are also presented.
