Elin is supposed to mean "Woman of Intelligence" in Sanskrit see http://www.thinkbabynames.com/meaning/0/Elin. However, I was not able to verify this independently in Sanskrit dictionaries on the web or on google books.
Also does it make a difference if it is spelled Elin or Elyn?
This might be off-topic but I would appreciate it if somebody could take the time to answer the question.
