Corculum married his second cousin Cornelia, eldest daughter of Scipio Africanus. They were betrothed in Africanus' lifetime, but married after his death in 183; on this occasion Corculum received a large dowry of 25 silver talents. The marriage may have been concluded between Scipio Nasica and Africanus' daughter to improve relations among the family, which had been strained by political competition between its members; for instance, Nasica had run against Scipio Asiaticus for the consulship in 191 and for the censorship in 184.
