Morkus from Orkus
Ta'veren are rare, but they aren't that rare. As Siuan says...It probably has to do with the three guys being united in a triad (Tyr-Odin-Thor, according to Jordan), tied across lifetimes.
"I saw the boy, you know, in the courtyard during the Welcome. It is one of my Talents, seeing ta'veren. [...] he blazed like the sun. I've seldom been afraid of my life, but the sight of him made me afraid right down to my toes. I wanted to cower, to howl."
She had to have seen others during her lifetime to know that it was one of her talents. The two women being Ta'veren, even if not as strongly as the men, would have made sense.
