GUAIMAR di Salerno, son of IOANNES II Prince of Salerno & his wife Sichelgaita --- (-[Feb/Jun] 1027). The dating clause of a charter dated Apr 989, which records a donation by "Lando…episcopus sanct sedis Pestane", refers to the sixth year of "principatus domni nostri Iohanni…principis" and the first year of "principatus domni Guaimarii principis filio eius"[939]. A charter dated Oct 989 names "domne Sichelgaita principissa uxor…domni Iohanni…principis" and "domnus Guaimarius princeps et Iohannes comes germani filii…domni Iohanni et domne Sichelgaite"[940]. The Catalogus Principum Salerni record that "Weimarius princeps eius frater [=Wido] benignus et clemens" succeeded as Prince of Salerno and ruled for 43 years 9 months[941]. He succeeded his father in 999 as GUAIMAR III Prince of Salerno. The dating clause of a charter dated Oct 999, under which "Alfanus filius quondam Petri de Capazzana" donated property to Cava monastery, refers to the eleventh year of "principatus domni nostri Guaimari…principis" without naming his father[942]. Normans returning from a pilgrimage to Jerusalem helped him defend Salerno from Muslim invaders [1000] and were invited to stay, the first Normans to settle in southern Italy[943]. [The dating clause of a charter dated Sep 1006 refers to the eighth year of "Guaimarii filii quondam Guaimarii principis"[944]. It is assumed that this charter is misdated and should refer to Prince Guaimar IV as no other indication has been found that the father of Prince Guaimar III was named Guaimar.] Prince of Capua and Duke of Amalfi [1010]. Duke of Sorrento [1011]. The dating clause of a charter dated May 1012 refers to the twenty-fourth year of "principatus Salerni domni…Guaimari…princeps", the fourth year of "principatus eius Capue et ducatui Amalfi", the third year of "ducatus illius Sirrenti", and the first year of "suprascriptorum principatuum et ducatuum domni Gisulfi…principis filii eius"[945]. The dating clause of a charter dated Nov 1018 refers to the thirtieth year of "principatus domni…Guaimari" and the first year of "principatus domni Guaimari eius filii…principibus"[946]. The date of his death is estimated from his being named with his son for the last time in the dating clause of a charter dated Feb 1027[947], and the dating clause of a charter dated Jun 1027 referring to the ninth year of "principatus domni…Guaimari" and the first year of "principatus domne Gaytelgrime genetrice eius"[948]. The Annals of Romoald record the death in 1030 of "Iohannes princeps Salerni" and the succession of his son "Guaimarius"[949], but the charter quoted above shows that this date must be inaccurate.
m firstly PURPURA, daughter of --- (-[Jul 1010/1011]). "Guaimarius…Langobardorum gentis Princeps" donated property to "Luce Abbati Monasterium Sancte Barbare", with the consent of "Purpure Principisse…coniugis nostre", by charter dated 1005[950]. "Guaimarius…Langobardorum gentis Princeps" donated property to "Ecclesia Veati Michaëlis Arcangeli…in Monte…Aureo", with the consent of "Purpure Principisse…coniugis nostre", by charter dated Jul 1010[951]. The parentage of Purpura, first wife of Prince Guaimar III, is unknown. A charter dated Jul 1059, under which "Aloara filia quondam Romoaldi comitis que uxor denique Petri comitis et referendarii fuerat" donated property, quotes an earlier charter under which "Guaimar Prince of Salerno", in "the fourteenth year" of his reign, granted property in Salerno to "Petri comiti thio et referendario nostro" at the request of "Laidolfi comitis socero nostro"[952]. If "Guaimar Prince of Salerno" in this document refers to Prince Guaimar III, the fourteenth year of his reign would have been 1006, in which case "Laidolfi comitis" would have been the father of Guaimar´s first wife Purpura. However, it is more likely that the document refers to Prince Guaimar IV (whose fourteenth year was 1032) whose wife named her father Laidolf in a later source (see below).
m secondly ([Jul 1010/1011]) GAITELGRIMA, daughter of PANDOLF III Prince of Capua and Benevento, Duke of Salerno & his wife ---. "Guaimarius et Guaimarius…Longobardorum gentis Principes" confirmed the rights of Salerno church, with the consent of "Gaitelgrime Principisse…coniugis nostre", by charter dated May 1023, the dating clause stating that the year was the thirty-fifth of "Domni Guaimarii Principis" and the fifth year of "Domni Guaimarii eius filio", subscribed by "Gaitelgrimam Guaimarii III uxorem" and "uxorem Guaimarii IV…Gemmam"[953]. Amatus records that the wife of Guaimar [III] Prince of Salerno was the sister of Pandolf [IV] Prince of Capua and that the latter was released after the intervention of Prince Guaimar[954]. The dating clause of two charters dated Jun 1027 and Jul 1027 refer to the ninth year of "principatus domni…Guaimari" and the first year of "principatus domne Gaytelgrime genetrice eius"[955], indicating that Gaitelgrima was appointed co-ruler or regent because of the minority of her son. "Gaitelgrima" is not named in the charters from Nov 1027 onwards, presumably indicating that she died before that date.
