Where is Gomer today?

The Gomer who married the prophet Hosea is probably in hell today unless she repented of her adultery before she died.

Gomer is also referred to in The Bible as a location or people group. The Table of Nations references Gomer to Gomer's progeny who settled in eastern Europe near the Black Sea and includes, among others, the Gauls, French, Galatians, Scots, Irish, Welsh, Saxons, Britons, and Dutch. Gomer was a descendant of Japheth, one of Noah's sons.

An Excellent reference is Dr. Henry M. Morris's book, "God and the Nations".
