The line of the descendants of Durin the Deathless, hereditary Dwarven-kings of Durin's Folk. Thrór, Thráin II and Thorin II Oakenshield were all descended from this House.
Gimli was born in the Ered Luin in the Third Age, son of Glóin. Gimli had wanted to accompany his father on the quest to reclaim Erebor, but at age 62 he was deemed too young. He was a remote descendant of Durin the Deathless, chief of the Seven Fathers of the Dwarves and ancestor of the Longbeards.
Thorin I (Third Age 2035 – 2289, died aged 254) was the King of Durin's Folk for 99 years, succeeding his father, Thráin I, on his death in T.A. 2190. Thorin was the heir of Durin the Deathless being the great-grandson of Durin VI.
Thorin, Fili, and Kili were the male heirs of the first line of Durin, the dominant line. They were the ones in line for the crown and the kingship, in that order. When they died, the first line of Durin was extinguished, but not the line altogether. The next male heir was Dain Ironfoot, Lord of the Iron Hills.

Is Durin Gimli's Cousin?
Gimli is indeed a distant relative of Durin IV as his father Glóin traces his origins from the line of Durin of the Dwarves of Erebor. These were the Dwarves who dwelt beneath the Lonely Mountain and were one of the seven kinds of Dwarves (known as Khazâd).
Yes he was a direct descendent of Durin the Deathless as Durin's Line Family Tree shows us. Yes he was a direct descendent of Durin the Deathless as Durin's Line Family Tree shows us.
Thrain I, Thrain II, and Thror are dwarves who live during the Third Age of the Sun and belong to the race of Durin. Durin's Line is one of seven original dwarf genealogies, and it's the main surviving Line after the end of the First Age. By the Third Age, even this family tree has shrunk in size.
Though Gimli has no children, he is not the last Dwarf of Middle-earth. After the fall of Sauron, his people continued to thrive in the Lonely Mountain. Gimli made his home in Rohan, in the Glittering Caves of Aglarond, and many of his kinsfolk came with him.
It is quite likely that Thorin knew both Fili and Kili died defending him. Their deaths and Thorin's did not end Durin's line, although did end the branch which had Thror, Thrain, and Thorin Oakenshield. Thorin's cousin, Dain Ironfoot, became King after Thorin's death.
Gimli didn't know about Moria's fate because there had been no communication between Erebor and Moria for 25 years, and the Dwarves were hopeful and did not want to accept failure until there was certain news.
Simply put, he was the only one available. There were only two dwarves at the council of Elrond, Gimli and his father Gloin. The Dwarves were fighting Sauron's forces constantly in their own campaign and couldn't spare many. Gloin was also much older now, it was absolutely his son's turn to go on a big journey.
The Balrog killed Durin VI, the Dwarf-King of Khazad-dûm, whereafter it was called Durin's Bane by the Dwarves. Avarice, principally for mithril, drove the dwarves to go too deep and awaken the Balrog.
For more than five millennia, the Balrog hibernated in his deep hiding place at the roots of the mountains in Khazad-dûm. He remained undisturbed throughout the Second Age and most of the Third, before the mithril-miners of dwarf-King Durin VI awoke him in T.A. 1980.
According to one theory (via Stack Exchange), Gimli did not know about the fall of Moria in The Lord of the Rings: The Fellowship of the Ring movie due, effectively, to poor communication.
Gimli was 139 years old (born in 2879 of the Third Age) when the Fellowship of the Ring set out from Rivendell, making him 52 years older than Aragorn.
Well, we don't really know how old Legolas is, not in canon. But certainly he is much older than Gimli. But to a dwarf's eyes (and to be fair, our own) he looks younger. And in terms of lifespan, Gimli has lived far more of his own life than Legolas has of his own.
This article refers to the son of Thrór. For other namesakes, see Thráin (disambiguation). Thráin II was the father of Thorin II, and the son of King Thrór, making him a direct descendant of Durin the Deathless.
Why did Thorin go crazy? Thorin fell victim to the sickness of greed. Dwarves are known for being greedy and proud, and when he realized the treasure of Erebor was his, including the Arkenstone, he became ill with Dragon Sickness. He began to value his wealth more than his friends, family, and own safety.
After the death of Thorin in the Battle of Five Armies, Dain becomes King under the Mountain. He redeems the Arkenstone from Bard with a fourteenth of the treasure, which is used to re-establish Dale. Over the next three years, Bard rebuilds the city of Dale and becomes its ruler. The city begins to prosper again.
He was succeeded by many generations of kings, among them appeared six others also called Durin (The Dwarves believed that these six were the reincarnation of Durin I, with memories of their past lives.).
Of the other companions of Thorin Oakenshield in the quest of Erebor, Ori, Nori, and Dori were also of the House of Durin, but were more remote kinsman. Bifur, Bofur, and Bombur were descended from Dwarves of Khazad-dûm but not of Durin's line.
After all, the Doors of Durin originated in Middle-earth's Second Age, just the right time for an appearance on The Rings of Power. And in this Tolkien rendition, the friendship between Durin IV and Elrond lives at the story's heart.
