William VI of Horne

Willem VI of Horne was a Dutch Nobleman, the Lord of Horne. Family Willem VI van Horne was the only child of Willem V van Horne and Mechteld van Arkel. When he was born, the inheritance of Willem IV of Horne was still contested between the children of his first marriage and those of his second marriage. The children of the second marriage were Willem V of Horne, his younger brothers Dirk Loef of Horne and Arnold II of Horne, and Elisabeth van Horne. Early Years Willem VI van Horne was born after 28 February 1357, and on or before 3 May 1357. Which dates are calculated from that he reached adulthood (12 years) in 1369. However it's not clear how and whether these dates take account of the new year starting in March in medieval times. The date of Willem VI's father's death is also not that certain. For both reasons, it is quite possible that his father died before Willem VI was born.
