  Research Notes:

Liudprand names "Boso ex eodem patre regis Hugonis frater". Gingins-la-Sarra suggests that this text means that Boso was born from a different marriage of his father. However, the wording could just as easily be interpreted as emphasising that Boso and Hugues were born from the same marriage of their mother. Considering the marriage dates of Boso´s daughters, it is unlikely that he was born before his brother Hugues.

Comte d'Avignon et Vaisin 911-931. Comte d'Arles 926-931. He was installed by his brother as BOSO Marchese of Tuscany in 931 after Lambert Marchese of Tuscany was deposed and blinded. He rebelled against his brother in 936, encouraged by Willa "uxore sua cupidissima", but was captured and deposed. ¹
