@lizardsquid I know for a fact that many Indigenous Australian communities use [given name] [skin group], Inuit traditionally go by any number of (usually mononymous) names depending on context, Arabic and Ancient Roman names are a whole subject of their own.

In my own universe, in Standard Isarthakan the default order is [given name] [family name] unless the given name has a case ending appended to it (in which case it goes last), often including clan names/alt. last names where applicable.
