In all the world, Герти (Gerti 
, Gertie 
, Gerty 
) is a common mostly female, but uncommonly masculine forename. The first name Герти is characteristic of Albania, where it is quite a common masculine name, Austria, where it is quite a rare female name, and the Democratic Republic of the Congo, where it is quite a rare predominantly female, but scarcely boy's name. Not in comparison with a country's population, this name is the most popular in the Democratic Republic of the Congo, Germany, and the United States. Very seldom, Герти is the last name as well as the forename.
