Slave Owner who set slaves free

by jessicaq44

I am looking for the name of a slave owner, or master, who would set slaves free. His name starts with a C, but I cannot find it. It sounds like (serion, or sereyion) Not sure at all... it sounds like it has an R in it, but it doesn't. Please help

Cicero, perhaps? He famously freed his slave Tiro, because of his excellent character.
