Girion

Girion was the last Lord of Dale, killed by the dragon Smaug when Smaug assaulted Dale and the neighboring Dwarf realm of Erebor. One-hundred and seventy years later, Bard, assumed to be Girion's descendant, took revenge on the dragon by slaying him with an arrow. It is also mentioned in The Hobbit that Girion had a necklace of emeralds, possibly later found among the treasures hoarded by Smaug in the Lonely Mountain.
