FYI. The name “Lain” is french L’Ain (the Ain), the Ain River in France. Ain means “river” according to a book called “24,000 Ancient Celtic Names”. The word Ain is also in the old testament several times and the meaning always relates to “a natural spring, water, stream, river”. In the ancient Egyptian Hieroglyphic the Ain (spelling differs slightly in Hebrew, Phoenican, Islam, etc.) means the “eye, source”. All these usages appear related the the source of water–probably the most important thing for desert nomadic peoples.
