The first of the Rubrii to obtain the consulship was Rubrius Gallus, some time before AD 68.
[1] The nomen Rubrius is derived from the Latin ruber, red or ruddy.
[2] The nomen Rubrena was probably derived from it using the suffix -enus, which was typically applied to form names from other gentilicia.
[3] The Rubrii used a variety of praenomina, including Gaius, Lucius, Marcus, Publius, Quintus, and Titus, all of which were among the most common names throughout Roman history.
[1] Of these, Gallus, a cockerel, and Nepos, grandson, seem to have represented distinct families, each of whom rose to the consulship during the latter part of the first century.
