Some tribes I leave the game's names, but change them if some outstanding characteristic surfaces. Like I had one farmer who was doggedly persistent from the very start, he never wandered off to pick coconuts when it was time for the crops to come in, became Master Farmer really young and was the tribe's 1st esteemed Elder. I renamed him "Steady Eddie" because whatever task I put him to he would stick with it.

Another tribe I named all the first generation with names starting with "Z" - when a "Z" mom & "Z" dad had a baby, that next generation I gave names starting with "Y" and so forth thru the alfabet. I have tribes with Spanish names, tribes with Hebrew names, tribes with Russian names, tribes with names from Robert Jordan's "Wheel of Time" series...
