"Oud-Wulven en Waaijen" remained a separate entity until 1811, when it merged into Houten.

This didn't last long: in 1818 they were combined with the heerlijkheden Wulven, Heemstede, Grote Koppel, Kleine Koppel, Maarschalkerweerd, and Slagmaat to a single municipality called "Oud-Wulven.

[2] Johannes Rothe was Lord of Oud-Wulven and Wayen in the Netherlands (1658–1671).

[4] It was first mentioned between 1381 and 1383 as tot Ouden Wuolven, and uses oud (old) to distinguish from Wulven [nl].

[5] Oud-Wulven is not a statistical entity,[6] and the postal authorities have placed it under Houten.
