a) daughter . Amatus records that the "sister of Guaimar's [Guaimar IV Duke of Salerno] wife was married to the Duke of Sorrento who had exiled her" and that Pandolf IV Duke of Capua attempted to seduce "the daughter of this lady"[536]. The editor of the edition consulted notes that the two sisters were the daughters of Laidolf, citing the sources which are quoted below relating to Gemma di Capua, wife of Guaimar IV Duke of Salerno[537]. However, as discussed more fully in the chapter dealing with the dukes of Salerno, it appears probable that Gemma di Capua was Duke Guaimar IV´s third wife whom he married in [1031/32]. Is it certain, therefore, that Amatus is referring to Guaimar´s third wife? The key to answering this question is determining how closely the relevant passage in Amatus can be dated. Amatus, in the paragraph preceding the passage reporting the attempted seduction of the young lady, records the succession of Duke Guaimar IV to his father[538], which is dated from other sources to [Feb/Jun] 1027. In the paragraph about the attempted seduction, Amatus records that "Guaimar…prepared to avenge this infamy. He brought forth his wealth…and presented these gifts to the Normans…[who] wasted no time in proclaiming his lordship over all the princes". Chalandon suggests that the dispute (which is also recorded by Malaterra[539]%29 broke out after Pandolf IV´s attack on Benevento in 1036[540]. This appears to be correct: Amatus records that Emperor Konrad II intervened in Italy in response to the problem[541], and his visit to Italy can be dated to 1037/38 from other sources (see, for example, the detailed account in the Chronica Monasterii Casinensis which specifies the date 1038 for the emperor´s arrival in Italy[542]). It can therefore safely be concluded that the attempted seduction of the daughter of the duke of Sorrento´s wife should be dated to [1035/36] and therefore that her mother was the sister of Prince Guaimar´s [third] wife Gemma di Capua. This means that the duke of Sorrento´s must have married the Capuan lady before 1020, assuming that her daughter was adolescent by [1035/36].
