Or maybe she was the ruler of Valenwood.

Though this could be like the Kings in Skyrim. There are many Kings and Queens that weren't High King/Queen, many of them from Solitude which was ruled by a branch of the Septim Dynasty.

Though I found out that the title is in fact Treethane, since there is a ruler of a Valenwood city from ESO that has that title.
