GEMMA (-after Dec 1070). Amatus refers to the wife of Prince Guaimar as sister of Landolf, one of his murderers[547]. "Waimarius…Longobardorum gentis Principes" confirmed the rights of Salerno church, with the consent of "Gemme Principisse…coniugis", by charter dated May 1032[548]. 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"[549]. It is assumed that this document refers to Prince Guaimar IV (whose fourteenth year was 1032) and that "Laidolfi comitis" was therefore the father of the prince´s third wife. Gemma, daughter of Laidulf, donated a mill at Vietri to the monastery of Cava dated Dec 1070, consented to by her five named sons[550]. m (before May 1032) as his third wife, GUAIMAR IV Duke of Salerno, son of GUAIMAR III Duke of Salerno & his second wife Gaitelgrima of Capua ([1010/12]-murdered 3 Jun 1052).
