I'm currently doing some research on Domitian, and right now am slightly confused over whether Domitian ever had a daughter. Several websites seem to state that there was a certain Domitilla who, like his only son, died in her early youth. Brian Jones' The Emperor Domitian so far only mentions the (nameless) son, but I did wonder whether new evidence had come to light in the mean time.
So, how many children did Domitian have, and by who?
