History. Aragorn is a direct descendent of the Faithful Numenoreans from the line of Elendil. Because he is a Numenorean, he is related distantly to Elrond through Elros. Aragorn was born in the year TA 2931 to the Ranger Arathorn and his wife Gilraen.
In The Lord of the Rings: Return of the King, Éowyn asks Aragorn his age and is shocked to learn that he is actually 87 despite looking no older than 40. But it is revealed that Aragorn is one of the Dúnedain—a descendant of Númenor—blessed with long life.
In fact, Aragorn's ancestry can be traced back to 6,000 years before the events of The Lord of the Rings: The Fellowship Of The Ring, which explains his complicated racial background. The blood of Númenor in Aragorn became genetically distinct during events currently being shown in The Rings of Power.

Is Aragorn related to Isildur?
Aragorn was a Ranger of the North, first introduced with the name Strider and later revealed to be the heir of Isildur, an ancient King of Arnor and Gondor. Aragorn was a confidant of the wizard Gandalf, and played a part in the quest to destroy the One Ring and defeat the Dark Lord Sauron.
The Gondorians were the inhabitants of Gondor. The Dúnedain of Gondor, also known as the Dúnedain of the South, constituted the ruling class and nobility of Gondor being descendants of the Exiles of Númenor who established the South-Kingdom.
Isildur is a fictional character in J. R. R. Tolkien's Middle-earth, the elder son of Elendil, descended from Elros, the founder of the island Kingdom of Númenor. He fled with his father when the island was drowned, becoming in his turn King of Arnor and Gondor.
Isildur was born in Númenor in S.A. 3209. He was the elder son of Elendil, son of Amandil, the last Lord of Andúnië. His younger brother was Anárion. While living in the island realm he married and his first son, Elendur was born in 3299.
Aragorn is not half Elf, although he is a descendant of Elros, who is half Elf (and the brother of Elrond, the half-Elf who raised him), which explains why Aragorn's life span is unusually long.
Elros chose to be a Man and live out his mortal life before passing into the mysterious afterlife of Men on Middle Earth. So Arwen is a descendant of Elrond and Aragorn is a distant descendant of Elros, who are brothers, which shows their kinship.
Their leader was the Witch-king of Angmar, and his second in command was named Khamûl. Khamûl was a lord of Easterlings, and was the only Nazgûl known by his name. Three of them were Númenóreans.
Why does Aragorn describe himself as the "last Númenórean" and "latest King of the Elder Days"? His children and the other Dúnedain would be Númenórean as well and the elder days refers (usually) to the First Age.
And the first Numenorean king was Elrond's brother, who chose a mortal life and to receive the Gift of the One to Men. This makes Elrond Aragorn's great-grand-great-grand-great-grand a few times over, uncle, and Arwen his great-grand-great-grand-great-grand a few times over, cousin.
Elros was the son of Eärendil, the great hero of the First Age, and his wife Elwing. He was the twin brother of Elrond and both were Half-elven. Choosing to live as a mortal Man, he became a lord of the Edain and the first King of Númenor, taking the name Tar-Minyatur.
Though Ar-Pharazôn was the last King of Númenor, the Line of Elros survived through Elendil the son of Amandil, and his two sons, Isildur and Anárion. They managed to escape the Downfall of Númenor that Ar-Pharazôn's actions had caused, and later created the kingdoms of Arnor and Gondor in Middle-earth.
For the earlier King of Númenor, see Tar-Elendil. Elendil was the father of Isildur and Anárion, a survivor of the Downfall of Númenor, and the founder and first High King of the Realms in Exile.
So, how come we don't visit Númenor in The Lord of the Rings? To put it bluntly: because it sank. Tolkien saw the island kingdom as the Middle-earth analog of Atlantis, which is why — as recounted in The Silmarillion section entitled Akallabêth — it winds up on the ocean floor.
Even though the Númenorians have very long lives, they grew envious of the blessing of immortality that the Valar had bestowed upon the elf race. The Númenorians are closer to the undying lands than anyone else on the map, but are never able to visit its shores.
Realising he could not defeat the Númenóreans with military strength, Sauron allowed himself to be taken as a hostage to Númenor by King Ar-Pharazôn in S.A. 3262. There, he quickly grew from captive to adviser and was known as Zigûr, the Wizard; he seduced the King and further corrupted the people.
Yes, Sauron willingly went as prisoner to Númenor and took the One Ring with him. He was most delighted to work his evil in Númenor under the guise of a penitent; and he used the Ring to dominate the mind of Ar-Pharazôn and to sway the people of Númenor into the worship of Morgoth.
The sons of Denethor II, Boromir and Faramir, are descended through their father from the Steward of King Minardil, Húrin of Emyn Arnen. A man of high Númenórean race.
In reality, the ancestors of the Rohirrim were the Éothéod, a tribe of the Northmen. Those were Middle Men, related to the Edain of the First Age, who did not go to Beleriand, like the other Edain, who were later rewarded with the island of Númenor by the Valar.
