The original reference here, http://www.fcpotawatomi.com/dec_15/foundation.html, cf. also http://www.gfw.org/NewsArchive/Spring'01nwsltr.pdf, both references now defunct, referred to a charitable donation from one of the Potawatomi commuities, saying "Smith's Potawatomi name, Ji-Gwe-Yan-Kwot,
Thundercloud, will be used in the naming."   "Thundercloud" (in English) is also a common Potawatomi surname in English contexts.
