 The first to attain the consulship was Gaius Laecanius Bassus in AD 40.The nomen "Laecanius" seems to belong to a class of gentilicia formed using the sufix "-anius", typically derived from cognomina ending in "-anus", or derived from other "a-stem" words.The name might be derived from the surname "Laeca", which was used by a family of the Porcia gens, or from the same root.
