Lets take a look on some of the other Heroes

Hurin - Lord of Dor-lómin and represents a mingling of the chiefly lines of the third and second houses of the edain.

Fingolfin - High king of the Noldor

Glorfindel - No mater witch one of them mighty amongst elves (one in Elrond's court and one sleev a Balrog)

Aragorn - Chieftain of the Dúnedain

Gimli - Son of Gloin, king of the dwarf-colony in the Grey Mountains

All are nobel of Great houses, mostley they can be compared to royalty. . .
