One Question for GWWhorl

Breaking if albeit temporarily my long-held lurker status (and since alga has already posed my initial question, "How long has the inhumu known as Quetzal been aboard the Whorl?"), I'd like to ask GW the following: What is the etymology of "Mamelta"? Bonus second question that I probably will not be allowed: Who was (since we are told in EXODUS she's recently expired and Nettle seems to have known her) Hyacinth's mother? Robert Borski
