For Gerl there are 211 on Yasni with different names.
Among the most common last names on Yasni Gerl is on position 4316.
To my knowledge comes from the Germanic name Gerl "ger" - her spear or a spear carrier / javelin thrower. The "l" behind it could be the South German / Austrian Verkleinrungssilbe and thus indicate a small Spearman / javelin thrower.
