Dr. Singh, you have provided good information and covered a lot of ground so far so naturally there are questions. While the case made for location of Uttarakuru is impressive, I do not think it is conclusive. First natural question has to be with time frame. In all the links that you have provided so far, date or timeframe is missing. That is very important.
For instance, if you say that these "Aryans" came from outside, then do you agree with current theory of circa 1200 BC or are you talking about earlier times. Since you cited Purans as one of the evidence, it may be important to take that view regarding that. Current view of various tribes is best summed in following url:

This deals with arriving at Kuru tribes. I arrive to our current date using this method.
My understanding is that there are 40 generations of Puru/Bharat tribe followed by Kuru before we finally come to Kauravas as we know it. If you take 3 generations in a century using present calendar (giving each person about 33 years of life expectancy), then 40 generations will provide around 1200 years so moving into 3rd millennium BC
for the start of this line of history (I am using 1000 BC as the base year of current Mahabharat war). Do you place Uttarakurus in this time frame or some other time-frame, like before, after or during. If they arrived earlier than say Puru/Bharat times, say around 2500 BC and they 'invaded' then who did they invade as Harappans were not really in decline at this. If you place them later then where do you place them in the above geneology, if you think that makes sense at all. We can discard my speculation if all of above is nonsense. Dr Bhagwan Singh, who I quoted earlier in reference to Dr Witzel and the conference at the India Internal center, claims in his book, that both Vedic believers and non-vedic socities were living at the same place. Do uttarkurus have a prior time frame than Harappan timeframe?
There is an alternative location provided for uttarakurus by Dr. Witzel again. I quote from his paper which can be found on internet:
"
Towards the end of the Vedic period, Kashmir indeed seems to appear in the texts: it may be indicated by the name Uttara-Madra, which occurs in the later part of AB 8.14 in a list of Vedic kingdoms and the titles of their kings. The country mentioned along with it, UttaraKuru, should, however, be sought in Himachal Pradesh, for example in an area including the Kulu Valley, the ancient Kulūa. Indeed, Madra was still known, even to the later Råjataranginīs, as the land immediately south of Kashmir."
I am also curious about the 1000 years Dev-Daitya war, where was this fought and who are the people being talked about in it?
