Aragorn’s mother (LotR/1113). Her name is a combination of gil “star” and raen “netted, enlaced”, meaning “one adorned with a tressure set with small gems in its network” (VT42/11), more more loosely “✱Netted Star”.
Conceptual Development: In drafts of the Lord of the Rings appendices, her name was Gilrain (PM/196). In notes from the 1950s, he indicated the second element of her name was raen “smiling, gracious, sweet-faced” (PE17/182).
A river in Gondor (LotR/875), a combination of gil “star” and rain “erratic wandering” (UT/242, VT42/12-3). Note that the river name Gilraen in The Silmarillion appendix is a typo (SA/ran), since that form is the name of Aragorn’s mother.
Conceptual Development: In Lord of the Rings drafts from the 1940s, this river was first named N. Lameduin.
