The Oldofredi were an Italian noble family from Brescia, related to Pandolfo III Malatesta and originally from Manerbio. In the 13th century, the family rose to prominence in the Franciacorta area and around Lake Iseo, where they also owned a castle at Peschiera Maraglio on the island of Monte Isola. From this possession derived the titles da Ysé or Isei. They were Ghibellines and aligned with Milan, firmly opposed to Venetian rule.
The probable founder of the family was Oldofredo (died 1212), feudal lord of the castle of Chiari.
