She had red-gold hair.
Siedre was killed when the wagons of the Da'shain Aiel were attacked, apparently near the Mountains of Mist. She and Adan had five children: Rhea, who was kidnapped by the same bandits that killed Siedre, and Marind, a son who had been killed by the first arrow that same morning; Sorelle, a Dreamwalker, who dreamed of her own death by fever at age twenty; Jaren, who discovered he could channel at age nineteen and subsequently threw himself off a cliff; and Elwin, who died of hunger at age ten. Siedre also had two grandchildren through her son Marind: Maigran and Lewin.
It can be reasonably determined that Ishara, founding queen of Andor, was directly descended from Rhea. Hence, Rand's paternal line, through Janduin, and maternal line, through Tigraine, can be traced to a common ancestor.
