William I van Brederode

He was the son of Dirk I van Brederode and Alvaradis van Heusden. William was only recognised as lord of Brederode in 1244, partially because he was a minor before that. Van Brederode accompanied William II, Count of Holland in his campaign against rebels above the Rhine in the Ruhr in 1248/49, and again in a campaign against the West Frisians in 1256. He was knighted in 1255, and appointed bailiff of Kennemerland in 1269. On 25 June 1282 he was awarded the rights to Goudriaan, Hardinxveld, Papendrecht, Peursum and Slingeland. William died in 1285 and was buried in the Brederode-chapel of the Engelmundus-church in Velsen.

In 1254 William married Hildegonde van Voorne, and they had six children:

• Dirk II van Brederode, 1256–1318, William's successor
• Alverade van Brederode, 1258 – after 1323
