Father-name
From Tolkien Gateway
Father-name was the name given to an elf at near birth by his or her father. It is part of the essë, or naming, of High Elves, along with the amilessë (mother-name) and epessë (nickname or honorific). The father-name was often the the primary name of an elf, until he or she chose an epessë.
An example is Finrod Felagund, whose father-name was Findaráto and epessë was Felagund. The name Finrod is the Sindarin version of his father-name.
