Brutus' uncle, Quintus Servilius Caepio, adopted him in about 59 BC, and Brutus was known officially for a time as Quintus Servilius Caepio Brutus before he reverted to using his birth-name.
Brutov strýko, Quintus Servilius Caepio, ho v roku 59 pred Kr. adoptoval; preto bol Brutus istý čas oficiálne známy ako Quintus Servilius Caepio Brutus, než sa neskôr vrátil k rodnému menu.
