Johanna of Horne

Johanna of Horne (1320–1356), daughter of Willem IV of Horne and Oda of Putten, inherited Horne, Altena and her other lordships in 1345 after her brother Gerard II fell at the Battle of Stavoren. She married Gijsbrecht III of Abcoude, who governed her lands iure uxoris.

In 1353 she granted Herstal to her eldest son Zweder, and on her death in 1356 the rest of her domains followed, though her half-siblings challenged the succession until arbitration in 1357.
