Sylvester of Marsico

Sylvester (c. 1100 – 1162), count of Marsico (it), was a Norman nobleman of the Kingdom of Sicily.

He immediately seized all the property of the Admiral Maio of Bari in Palermo on the latter's assassination (10 November 1160).

Sylvester, though distantly related to King William I, was possibly a conspirator with Bonnellus.

When in 1162 William was besieging Salerno, Sylvester and Palmer interceded on behalf of the Salernitan notary Matthew of Ajello to prevent a sack.

He left a daughter named Matilda who is buried in San Cataldo, the foundation of Maio which Sylvester had secured for himself.
