It derives from the mansion of the family's founder, Ramiro de Mosquera. In the fifth century, it was already linked to Moscoso, one of Galicia's oldest notable families. In Galicia, one of the oldest houses was in Coto de Villar de Payo Muniz, a dos leguas from Ourense. Another existed at villa de Vilariño de Conso.
