Sextius Aelius Catus was a Roman senator and consul ordinarius for 4 AD with Gaius Sentius Saturninus as his colleague.
His only known grandchild was Aelia and Claudius's daughter Claudia Antonia, born in 30.
His daughter Aelia Paetina is said to belong to the Aelii Tuberones, implying a descent from the consul of 11 BC.
This is based on a mention by Strabo that Catus moved 50,000 Getae across the Danube and settled them in Moesia.
[2] When he held this appointment is uncertain: Ronald Syme speculates that he was either a praetorian governor which would date his tenure before AD 4, or a consular governor which would date him to AD 9–11.
