In the background of my avatar photo you will make out two islands. When the Vikings (Rolf and his cousins) made their raiding attacks on mainland Britain too rape our beautiful Celtic princesses and pillage our belongings they couldn't help notice these islands and especially their breast like appearance, so the name Mumbles is derived from Mammaries. Prior to this it would have had a non pronounceable Celtic name like Ynysmwlchareg, so in this instance I'm glad the Vikings were good sailors and admired the female form!!
