Ioannes III, prince of Salerno

1. IOANNES ([1025/30]-[early 1040]). The dating clause of a charter dated Jan 1038 refers to the twentieth year of "principatus domni…Guaimari" and the first year of "principatus domni Iohanni eius filii"[999]. It is unlikely that Ioannes could have been born before 1025 considering the likely birth date of his father. However, it is also unlikely that he was born much after 1030 considering that he was named associate ruler by his father. If this is correct, Ioannes must have been born either from his father´s first or second marriage. The Catalogus Principum Salerni records that "Ioannes eius filius [=Weimarius]" was associated as IOANNES III Prince of Salerno by his father and ruled 4 years and 9 months, and ruled in Sorrento alone after his father was expelled[1000]. He is not named as prince with his father in the dating clauses of Cava charters dated after end-1039, which suggests that Ioannes died earlier than is indicated by the Catalogus. This is especially probable as his brother Gisulf is named with his father Prince Guaimar in all charters in the same cartulary which are dated after Guaimar associated Gisulf in the principality.
