He took the name "Mince" from the old Cherokee, (more properly spelled Tsalagi), language. This is an Iroquoian language with an innovative written syllabary invented by a Cherokee scholar.
Around 22,000 people speak Tsalagi today, primarily in Oklahoma and North Carolina. Though it is one of the healthier Indian languages of North America and the one in which the most literature is published.
Tsalagi is still in imperiled condition because of government policies as late as the fifties which enforced the removal of Cherokee children from Tsalagi-speaking homes, reducing the number of young Cherokees being raised bilingually from 75% to less than 5% today.
It means "Twat".
