Tillia gens
The gens Tillia, occasionally written Tilia, was a minor plebeian family at ancient Rome. Few members of this gens are mentioned in history, but others are known from inscriptions. Origin. The nomen "Tillius" did not originate at Rome, but appears to belong to one of the languages of northern Italy, such as Umbrian, or the languages of the Picentes or the Sabines. The nomen is frequently confused with the more common "Tullius", which for this reason is sometimes substituted for it. Praenomina. The main praenomina of the Tillii were "Marcus", "Lucius", "Gaius", and "Publius", four of the most  common names at all periods of Roman history. The remainder mostly used other common surnames, including "Publius", "Gnaeus", and "Titus". The name "Decimus" is also found in a filiation. Branches and cognomina. The most famous cognomen of the Tillia gens was "Cimber", borne by at least one, perhaps several members of a family that gained prominence in the Roman state toward the end of the Republic. This surname originally referred to one of the Cimbri, an Gaulish or Germanic people who fought against the Romans in Gaul and Spain at the end of the second century BC. Although such names  frequently indicated the descent of the first bearer, it could also be that the cognomen was obtained by someone who in appearance or character was thought to resemble one of the Cimbri. Another family of the Tillii bore the cognomen "Rufus", one of the most common Latin surnames. Meaning "red" or "reddish", this name was typically bestowed on someone with red hair, although it might be inherited by a person's descendants without respect to the actual colour of their hair.
