We report the results of an observational program to investigate the gamma-ray and optical variability properties of the vRL NLSY1 galaxies listed in the Yuan et al.sample.We have identified 17 members of the Yuan et al.sample Course a pied - Homme - Vetements - Manteau - Impermeable possibly associated with gamma-ray sources based on a combination of their optical polarization and optical variability and their gamma-ray properties.Eight have previously been associated with gamma-ray sources.

We find nine additional members that we predict are excellent candidates to be Backpack associated with gamma-ray sources in the future.All 17 sources have many properties in common with flat spectrum radio quasars (FSRQs), suggesting that they may, in fact, constitute a new subclass of FSRQs.
