I don't believe that there's a "natural" link between family relationships and a claim to a specific territory. From my point of view there's no such thing as "rightful" or "legitimate" owners simply by biological or cultural heritage. "Property" and "rights" are social categories which are tied to a political construct, i.e. a state and only make sense in that context. And those political constructs are always established and sustained by force.

So, I don't agree that the Dunlendings of 3019 T.A. can justify their war against the Rohirrim based on something that happened over 500 years ago. Or would you suggest that I have an inherent right and a claim to some territory my distant ancestors inhabited in the year 1516, wherever this may be?

Apart from the moral question, I think it's fair to assume that the "history" between the Rohirrim and the Dunledings created a highly ideologized feud and hatred between them.
