Aloisia Nemosni is one of the Kin.
Given Aloisia's age, her strength in saidar must be relatively high. The Wheel of Time Companion gives her strength as either 17(5) or 18(6), which is quite high by Aes Sedai standards and strong enough to travel.
She is eldest of all the Kin and is nearly six hundred years old. She is now an oil merchant in Tear. When talking of bringing in the Kin and letting them try again to be Aes Sedai, Elayne Trakand and Nynaeve al'Meara wonder if someone as old as Aloisia would die if she took the Three Oaths on the Oath Rod.
