Since I don't know what you have and haven't found, here are the usual suspects...
Tacitus the Annals of Imperial Rome Book XII, Book XIII
Suetonius, Life of Claudius
Suetonius, Life of Nero
Cassius Dio, Book 61, 62 & 63.
You may find that you'll get a better response if you give us an indication of what you already know and what you've researched.
I have found no primary sources that is sources that have happened at the time hummm like a historian writing about somthing as it happened thankyou for your help
