In my first tribe, I didn't and I had trouble keeping track. I didnt rename them because I wanted the tombstones to have same tribal-sounding names.

The minute I learned the trick of the stews, I created another village and named them after my officemates from my jobs haha. The good ones get totem's named after them

Another, when I only wanted runners and elders, I named them 1-100, with only the runners and elders having names.

A final tribe I created from experience, I name them my long lost friends and acquaintances, That way, I can remember the good stuff while playing
