The example name list from Paizo includes Amare and Melaku, so Ethopian names are used as the basis for this generator.
Paizo does not specify whether or not Garundi use surnames, but the implication is that they do not. Garundi names define the clan's territory as well as one's ranking within it, and names are based around physical, geographic features for high-ranking clan memebrs, and local sites for low-ranking ones.
When choosing names that start with a letter or letters, keep the prefixes short. One or two letters work best!
Adjusting these settings can help fine-tune your name list, but if you make them too aggressive you might not get any results at all.
