Ronald Syme has argued that he was originally named Servius Julius Servianus, suffect consul in 90, and that Lucius Julius Ursus adopted him after that year, leading to a name change; no scholar has spoken against this identification, and it has been considered accepted by all.
[2] Before the accession of Trajan in 98, Servianus had married Aelia Domitia Paulina, the elder sister of Hadrian, who was thirty years younger than he was.
Before Pliny's death around 111, Servianus and Paulina had arranged and married their daughter Julia to Gnaeus Pedanius Fuscus Salinator, ordinary consul in 118 as the colleague of emperor Hadrian.
Hadrian's attentions turned to Servianus' grandson, who was also named Lucius Pedanius Fuscus Salinator.
Hadrian promoted the young Salinator, his great-nephew, gave him special status in his court, and groomed him as his heir.
However, in 136, Hadrian changed his mind and decided to adopt Lucius Aelius Caesar as his son and heir.
