Names are often repeated in dynasties, and the genealogies show that a distant ancestor of Thror was referred to, Thrain I, a fugitive from Moria, who first discovered the Lonely Mountain, Erebor, and ruled there for a while, before his people moved on to the remoter mountains of the North.
They drove many of them into the Running River, and such as fled south or west they hunted into the marshes about the Forest River; and there the greater part of the last fugitives perished, while those that came hardly to the Wood-elves’ realm were there slain, or drawn in to die in the trackless dark of Mirkwood.
There are no more uses of "fugitive" in the book.
