Gróin

Gróin (2923-2671 TA) was an important figure in the royal genealogies of the Dwarves, Gróin was the grandson of Borin, the younger son of King Náin II, and so could claim direct descent from Durin the Deathless himself. In his turn, Gróin was father to Óin and Glóin, and uncle to Balin and Dwalin, all four of whom travelled on the Quest of Erebor.

Through his son Glóin, he was also grandfather to Gimli Elf-friend of the Company of the Ring. For all his genealogical importance, though, we know almost nothing of his life. His dates of birth and death, though, show us that he was alive at the time of Smaug's Sack of Erebor, and the Battle of Nanduhirion twenty-nine years later. It is more than likely that he was present at both these events.
