S. Erchirion pn.
The 2nd son of
Imrahil, appearing only in a genealogy chart of the house of
Dol Amroth (PM/221). His name may be a combination of
er “one”, a mutated form
chir of
hîr “lord” and the patronymic suffix
-ion¹ “son”, though David Salo suggested the initial element may be a variant form of the prefix
ar(a)- “noble” (GS/348).
