13. Q.Titinius, one of the judices at the trial of Verres, was a brother (by the same mother) of C. Fannius, a Roman eques (Cic. Ver. 1.49). This Titinius carried on the business of a money-lender, and as such Cicero had dealings with him. On the breaking out of the civil war in B. C. 49, he espoused the cause of Pompey, but his son, who had been adopted by one Pontius, and who is therefore called Pontius Titinianus, sided with Caesar. (Cic. Att. 2.4, 5.21.5, 7.18.4, 9.6.6, 9.9, 18, 19.)
