Ardoin was a contemporary of and played music with Canray Fontenot. Alphonse "Bois Sec" Ardoin was Amédé's younger cousin.
There is a tragic, and some say apocryphal, story about how Ardoin ended his days. It's too true to bigotry not to have some truth. You can read about it HERE if you like or watch a video HERE. I'd suggest you just enjoy the music.
