Decimus Junius Brutus
Decimus Junius Brutus Albinus probably was a son of Decimus Junius Brutus, who had been Roman consul in 77 BC, and, as his last name suggests, was adopted by Aulus Postumius Albinus, who is only known as "triumvir monetalis" in 81 BC. Decimus's mother was probably Sempronia, who married and is known to have had children with the elder Decimus, or perhaps an otherwise unknown Postumia, a relative of his adoptive father.
