Werner Schumacher offers several possible derivations for the distinguishing prefix, but none is certain. It could be from the Latin for elm, or perhaps from "Olk" or "Ulca", meaning “land that can be worked by plough” or “land that is worked”. Schumacher also cites a Dr. Beestermöller who believes that the root may be a Celtic reference to wetlands.
