Question: is gimli son of gloin from the hobbit?
Answer: TL;DR: Gimli (depicted in the locket, and from The Lord Of The Rings) is the son of Glóin (in The Hobbit). Glóin is the dwarf that shows Legolas the locket. The locket depicts his wife and son, Gimli - the same Gimli of the Lord of the Rings.
