St. Giles in Imber, Wiltshire (England)
If Amber was once very popular and Ember is catching on like wildfire, could Imber have a chance? This mysterious name from the Latin word imber, meaning "heavy rain," was used for a town called Imber in Wiltshire, England. The entire populace was evicted in 1943 during World War II so that American troops had a place to prepare for the war. In Yiddish and Polish, it means "ginger," with the variant spelling Imbera.
Although Imber (as well as Imberre and Imbersky) can be found here and there as a surname, it is not used as a first name. This would make a good choice for those interested in history. White Pages claims there are currently 37 people named Imber, as well as 3 named Imbera.
