Given the high station that this family reached, it seems possible that the Servaei of Gigthis in Africa Proconsularis was descended from them. This family seems to have come to prominence with Quintus Servaeus Macer during the reign of Antoninus Pius. His surname, "Macer", designated someone who was notably lean, but the chief cognomen of this family seems to have been "Fuscus", "dark", which would likely have referred to someone with dark brown hair. This alternated with "Firmus", "strong" or "steadfast", and "Felix", "happy" or "fortunate". The Servaei Fusci were of equestrian rank, and seem to have formed part of the nobility of Gigthis, where they served in the local senate, and at least one of them, Quintus Servaeus Fuscus Cornelianus, served in the Roman Senate and held a number of important positions throughout the Empire. Another family of colonial Servaei lived at Sufetula in Numidia, but it remains unclear whether or how they might have been related to the Fusci. Some of them bore the surname "Potitianus", perhaps commemorating their descent from the ancient Potitia gens.
