Marcus Salvius Otho (grandfather of emperor Otho)

His father is described by Suetonius as an Eques (knight) of Etruscan descent whose ancestors came from Ferentinum and were descended from the princes of Etruria.

[2] There have been many attempts at identifying Marcus' father, among them an Otho mentioned to have been a "puny-headed" follower of Julius Caesar in one of Catullus poems was proposed by Ernst Bickel,[3] T. P. Wiseman and Bruce W. Frier have proposed that he may be the Salvius who was tribune of the plebs in 43 BC (and that this man was the son of an Urban praetor in 76 BC)[4] who Elizabeth Rawson also identifies as the Salvius who was the first victim of the proscriptions of the Second Triumvirate.

[5] Joachim Losehand argued against a connection with the Gabinian centurion Salvius who assassinated Pompey.

[7] He was raised and educated in the household of empress Livia,[1] probably alongside her sons Tiberius and Drusus after their father died in 33 BC.

[10] Otho married a woman whose identity is not known for certain, but Suetonius describes her as a noblewoman "allied to several great families".
