Aislin. Gaelic/Irish. "Dream" or "vision." Pronounced "Ash-leen" or "Ash-ling" (also spelled Aisling). Sound is similar but NOT just Irish for Ashley, which was an unrelated male name originally (remember Gone With the Wind?)
Pagan Facts, this is only the tip of the iceberg. The robes, the dates for holy days and their names, the censors, altars, symbols, bread and wine, the "book", the trinity and on and on have all been usurped from wicca and pagan religions long in practice before male based religions slaughtered to dominate all others as governments/religions in one.
