How many ancient sources (pre-410AD) directly mention or quote the man ‘Publius Valerius Publicola’? Is it just Livy and Plutarch who wrote of him, or does his information also exist elsewhere?

Publius Valerius the consul of 510 BC and the co-founder of the Roman Republic was basically the George Washington of Rome. Where can I find more sources on him? Other than Livy’s history of Rome book I and book II, and Plutarch’s Poplicola mention in his series.
