What happened to the great Patrician families of Rome after 476?

by GlassCaraffe

The Julia family, the Valeria, and many more. Their class ruled the Republic and Empire for decades, if not centuries. What happened to them towards the late Empire and the fall? Did they migrate East to Constantinople? Die out? Change their names and settle to rule somewhere?

Can any modern families or aristocratic dynasties trace their lineage to one of these ancient gens?
