Lol... it always reminds me of the name "vladimir", which sounds "evil" to me because of Baron Harkonnen in Dune. But I don't hold that against it.
Ha ha, yeah! Weald is indeed from Anglo-Saxon origin. And about the good and bad sides, it really depends. Maybe your good side is an order of people who work in secrecy and are great magic-users and fighters who strive for the greater good, you can give them names like The Keepers, The Warders or The Rangers. You get the point.
In regards to name / title IP rights, you should use caution as such can be copy protected, especially 'fantasy' names. Reference : Tolkien Enterprises vs TSR - Fiend Folio (out of court settlement). TSR had used a Balrog, their own illustrated version, within their book. But that did not violate Tolkien IP rights ... it was the name Balrog, which was made-up and copy protected by Tolkien. That is why Fiend Folio vanished from the shelves and is a rare item indeed (own 8 copies, 7 mint, 1 used). Also, using fantasy language (web generated) converters could very well violate IP rights, being Elvish: Orcish, Klingon or what ever. Though, they can give you ideas, you just need to manipulate for your own needs. On a side note, a short introduction of your work (without giving away your unique idea) would provide a good reference for those who wish to contribute toward your needs. It is hard to create a name without knowing exactly what is to be named. For instance : I need a name for a new born! People will assume automatically that the new born is Human ... is it ? Thus, everyone will provide names that will not work.
It's an Indian (Native American) nation. Based around Wisconsin and surrounding areas, if I'm not mistaken.
