As a welcome digression from heavy words, heres a place which I know pretty well.
Alwar: District in North Rajasthan, better known for its milk cake and extreme cold. The song 'Yeh Bandhan' from the re incarnation movie Karan Arjun was shot here.
I used to sell Tata pick ups some years ago, and in this capacity was managing the dealership in Alwar. It was on some trip to some nondescript village that I was recited the story of the origin of the name 'Alwar'. Truly fascinating. Hark..
It was earlier called Ulwar after the Ulwa river on whose banks the town resided. As far as I remember there is no trace of Ulwa anymore but it has manifested into the lingua franca. Now during the British Raj, Ulwar and neighbouring regions were provinces paying largesse to the Empress. The royals from each protege used to sit around a round table with the white skin seated at the table's head. The princes were seated in alphabetical order. Under such scheme of things, our Ulwar prince always ended up far away from the epicentre. Hence, he changed the name to Alwar!
I think this is one word origin which is google proof :-)
