For Elger there are 83 on Yasni with different names.
Among the most common last names on Yasni Elger is on position 4444.
Elger as a given name probably comes from Adalger from the North Germanic, the last name can not say, but I would never have thought that there are so many last names with Elger'm always there is only a first name and the name I was the only one.
