Generally, the nations of the Nyrellan world all follow the same naming convention. A person is given a name by their parents, and then inherit a family name from one of their parents, most often their father. Sometimes, they are also given several middle names.
In Daslea, only the royal family and nobility followed the general Nyrellan naming convention prior to the modern day. Before the Revolution, Daslea strictly adhered to a class system. Those who were above peasants, but below the nobility, were elevated for their service and commitment to their communities. Their names consisted of their place of origin, the Divine Virtue that earned them their social promotion, and their given name. Their place of origin and Virtue were usually initialized.
All other Dasleans simply went by their given names, differentiating each other with their places of origin or in reference to who their parents were.
Animist naming conventions, in one way or another, are unique in their focus on honoring a person's ancestors. In the Far East, a person's name begins with the family name they inherited from their father and ends with their given name. In other parts of the world, this order is inverted.
Otrenite people have a given name, and then two family names. Their second family name is always inherited from their father. The first family name of a couple's first three children are their maternal grandfather's family name (their mother's second family name), their paternal grandmother's second family name (their father's first family name), and then their maternal grandmother's second family name (their mother's first family name). This way, with those first three children, all four of their grandparents would in some way be represented in their names.
Put another way, the first three children of any given couple would follow this pattern:
<Father's Second Family Name> <Mother's Second Family Name> <Given Name>
<Father's Second Family Name> <Father's First Family Name> <Given Name>
<Father's Second Family Name> <Mother's First Family Name> <Given Name>
The first family name of any children born after that are up to the parents.
The people of Goengyi have a given name and two family names. Men pass down the name they inherited from their mothers, while women pass down the name they inherited from their fathers.
Estarese people have a given name and a family name. Boys inherit their mother's family name, while girls inherit their father's family name.
The people of Acroton have a given name, a patronym, and a family name that they inherit from their mothers. Men don't change their names upon marriage.
In Gibroar and Yespela, people don’t typically have surnames, instead being identified by their parents, as a way to honor them.
Someone’s full, legal name could be: <FirstName> <son/daughter> <Father> <and> <Mother>
The personal name for day to day use only uses the name of the parent whose sex matches the child. Outside of Gibroar, the word for “son” or “daughter” is dropped. Alternatively, some sort of ancestral title can be used as a surname instead.
The nomadic Roma traditionally don't have family names. When they need to put a family name on a form, they'll typically use one of their parent's names instead. Roma who settle down in a city somewhere might take a parent's name as a surname or simply create one.
Being Nyrellan, the people of the Songwo Tribe follow that naming convention. How surnames work for the rest of the nation differs slightly based on a person's tribe.
Amansie - In addition to a given name, Amansie people inherit their mother's family name.
Eunoto - In addition to a given name, Eunoto people inherit their father's family name.
Ajak - When a couple is married, whichever has a higher social status (better occupation, better education, came from a more prestigious family, etc.) has their name selected as their shared surname. Their children then inherit that family name.
Arishem - When a couple is married, both partners work together to create a name for their new family, often trying to incorporate elements or meanings from both of their birth names. Their children then inherit that created family name.
The majority of the Ekaskan population follows the same naming convention: <Given Name> <Clan Name> <Family Name>
Clan names trace back centuries to which of the nation's noble houses someone's ancestors swore allegiance to before the nation's unification under its ruling dynasty. In the modern day, all of these clan names are simply expressed as a middle initial. Children inherit the clan name of their mother, in honor to the Ekaskan Mother of All.
The exception to this rule are members of those ruling houses, who simply go by their Given Name and Clan Name, since their family represents the clan.
