Meaning:
Its source is raggin, an Ancient Germanic name meaning "Advice."
Narrative:
The derivation given for this newly developed personal name is a guess based on the derivation of an identical surname. However, it could originate ultimately from the Latin regina (''queen''); if so, it probably should be traced through the intermediate French word reine.
Lastly, it must be pointed out that this might be nothing more than the word ''rain'' fancified with a silent ''e'' at the end.
