According to E-Online:
"Isaac Hayes and wife Adjowa welcomed son Nana Kwadjo Hayes into the world Apr. 10, according to spokesman Rob Moore. The baby boy tipped the scales at eight pounds, five ounces.
"As Tom Cruise's Suri before him, the unusual tot name requires some translation. Per the Associated Press, Nana is the Ghanaian word for "king," while Kwadjo means "boy born on Monday." (Bypass the calendars: Apr. 10 did indeed fall on a Monday.)
"The Shaft singer likely gained inspiration for the moniker during one of his goodwill trips to the African country. In 1992, Hayes was crowned an honorary king of Ghana's Ada district thanks to his humanitarian deeds."
These humanitarian deeds included introducing the nation to the study technology developed by Scientology founder, L. Ron Hubbard.
Isaac Hayes is a Freedom Medal Winner, awarded by the International Association of Scientologists.
Here is a brief statement from Isaac from the What is Scientology? site.
