To be a bit contrary (some may find my views to be so ... whatever ...
), Aragorn is very eminent among the vastly expanded supporting cast added around the central theme of three Hobbits - Frodo, Sam and Sméagol-Gollum - deep-sixing the extremely peripheral main baddie. In a fundamental way, LoTR very much is the "New Hobbit".
Aragorn is the Bard of LoTR, Gandalf is in both stories (the only character to be very central to both), the Maia baddie has different aliases but is very peripheral in both.
Of course Aragorn's heritage goes vastly deeper back into time than Bard's does ... well, recorded time, at least. Bard might be a descendant of one of those clans of the Three Houses of the Elf-friends who never crossed into Beleriand to get mixed-up (and messed-up) in the wars of the Silmarillion.
But looking at his ancestry: Aragorn is descended from Elros in the 64th generation, so Elrond is his uncle at the same remove. Elrond and Elros are descended on their human lineage from Beren and Tuor, with all of their back ancestry. From Lúthien, and thus Elwë (Thingol) and Melian the Maia. From Idril, thus Turgon, thus Fingolfin, thus Finwë and Indis of the Vanyar royal house.
Then add Arwen, daughter of Elrond (and thus Aragorn's cousin by the remove of 63 generations!), thus having the same descent as Aragorn on her Father's side, is granddaughter of Galadriel, daughter of Finarfin, Fingolfin's younger brother, and Eärwen, daughter of Olwë, Thingol's brother. A somewhat apocryphal lineage makes Celeborn, Galadriel's husband, descended from a third brother to Elwë and Olwë.
So Aragorn and Arwen's son Eldarion is related to more royal lineages in Middle-earth than Queen Victoria was, even including three generations up and down!
(If anyone doubts residual Hobbit ancestry in my lineage should just consider if you would spend so much time on convoluted lineages, even if you have three books to help you with them.)
