*(whose name is similar to one of the names of the incestuous brother in some of the Ingrian songs)*

A note on that Tolkien version. From a Tolkienite's standpoint, this unfinished story is fascinating. The invented names are very similar to his later Quenya names and words and you can kind of see the roots of what eventually became the Narn. Also, this story is small-scale, only involving two clans feuding over resources, a contrast to the Narn, which is an epic involving all of the Free Peoples of Arda and the Dark Lord, fighting over control of the realms of Middle-earth. So, Tolkien basically took this story about a family feud and turned it into an epic. The Narn is one of my favourite Tolkien books, btw.
