All the titles for the positions on the Grand Council and the Women's Council of the Haudenosaunee (Iroquois Confederacy) are derived from the names of their original members. For example, a man named Tadodaho and a woman named Jigonsaseh (the spellings of both vary) were the original chairs of the two councils. The current Tadodaho is Sydney Hill, who has held the position since 2002. There isn't a currently recognized Jigonsaseh. The Women's Council is thought to have dissolved around the time of the American Revolution and the temporary disbanding of the confederacy as a whole, though there's some evidence that the council may have continued to operate in secret - or at least people knew who was supposed to serve on the council if it ever re-convened - well into the 1800s.
Because of this, we have a complete list of the original 50 members of the Grand Council, and possibly a partial list of the original members of the Women's Council (the list contains a mix of traditional Iroquoian names and contemporary Anglo-names; the women who used traditional names on the list likely were using their Council titles rather than their birth names but its not certain).
In several languages of Eastern Europe, the word for "king" is something like karol, karalis etc. This goes back to Charlemagne, aka Carolus Magnus or Karl the Great.
The Dauphin of France. Dauphin (dolphin) was a sort of pet name that the son of the count of Albon, Guigues, was given by his English mother when a child. When he inherited the territory he formally called himself "The Dauphin", had a dolphin as his motif on his arms, and the County became known as the Dauphine. It was ultimately purchased by the King, who gave the title to his eldest son.
in roman society, there was three titular delimitors for male citizens. the first one was the given name, Marcus or Gaius or Sixtus or Quintus to name a few, the latter two litterally meaning "the sixth" and "the fifth". there were only 10 or so in use in classical times, thats why it was common not to write down but the initial letter (for the examples above: M,C --- the maiuscule letter G was a late addition to the Latin alphabet ---- , S,Q). the second one is the family name, priviledge of patrician families. Iulius, Livius, Marius, Tullius, all family names. the tullius family, by the way had most of its properties in what is called Greece today.
the third delimiter is a title, by which the person was known to his peers. this title could change throughout the lifetime of the person, reflecting military merits and the reputation as a statesman. "Caesar" was a title of that kind. it is tied to the historical person that we know as C.IuliusCaesar, but many later emperor of Rome acquired that title as if it was also part of their name as part of the process to formally legitimize his succession to power. even though they usually had a huge army at their disposal to back up any claims, the institutions of power in imperial rome still required at least some backing of a deity/deified persona. the titles Kaiser and Czar have to be understood in that sense as well.
similar to "Caesar" was "Augustus", which was the delimiter of the third kind acquired by Octavian, stepson of the original Caesar. it was the title used by (western) roman emperors until the end, not Caesar or In-perator as one might expect. the last western roman emperor apparently did not live up to the litteral meaning of the title and was dubbed "Augustulus" by his biographers. the title has become obscure since, but the concept of "massing", "enriching", "multiplying" conveyed by the euonym is still apparent in the original meaning of the "Reich" or instance.
