I also doubt that it's Lothars daughter. He was pretty old back then. Like , Lothar is the older brother of Varians Mother. So this woman would be around the age of Varian, making her to old to be really considered a child during the third War.
Bolvar as the Father is possible, as we never saw anything of his private live. But it's odd that she spend all the time in Kul Tiras and not back in Stormwind with her dad. So this doesn't make much sense.
Which means her Parents probably didn't survived the third War. And Daelin personally appointed someone for her, so her parants had some connection to Daelin somehow.
