The name is a contracted form of Elias

Alternately, it could also very well be from the geologic term, the German Lias, a stratigraphic term that today is used solely for lithostratigraphic units from the Lower Jurassic. In older literature, Lias was also used as a synonym for the Early Jurassic epoch of the geologic timescale

It is currently the 139th most popular male name in Germany, (2011).
