Jacob van Wassenaer Obdam

Jacob, Banner Lord of Wassenaer, Lord Obdam, Hensbroek, Spanbroek, Opmeer, Zuidwijk and Kernhem was a Dutch LieutenantAdmiral, and supreme commander of the confederate Dutch navy. The name Obdam was then also spelled as Opdam. British contemporaneous sources typically refer to him as Admiral Opdam or Lord Obdam because it was not until 1657 that he bought the Wassenaar Estate from relatives and thus acquired its title. Modern Dutch sources sometimes less correctly insert a second van between Wassenaer and Obdam or use the modern spelling Wassenaar.

Jacob was born in 1610, the eldest son of LieutenantAdmiral Jacob van Wassenaer Duivenvoorde and Anna van Randerode van der Aa. In 1631 he joined the army. OnApril 1633 at Maarssen he married Agnes Renesse van der Aa. In 1643 he became drost of Heusden, an important fortress town, and soon after military governor of its garrison.
