Facts and Events
There are 2 vital records available on MyHeritage for William IX , Count of Poitiers, including birth records, marriage records, and death records. Vital records are historical records that are typically recorded around the actual time of the event, which means they are likely accurate. Vital records include information like the event date and place, and the person's occupation and residence. Vital records also often include information about the person's relatives. For example, birth and marriage records include names of parents and divorce records list the names of children.
At the time of his death, he was reigning as Count of Poitiers, as his mother had ceded the county to him. For centuries, the dukes of Aquitaine had held this as one of their minor titles, so it had passed to Eleanor from her father; giving it to her son was effectively a revival of the title, separating it from the duchy. Some authorities say he also held the title of "Archbishop of York", but this is probably an error. His half-brother Geoffrey (died 1212), who was born a year before William, did later hold that office, causing the confusion.
