[78-L] Jelly Roll Morton's first records and piano rolls

[bruce78rpm at comcast.net]

Does anyone have any definitive information as to when Ferdinand Jelly Roll Morton first made recordings or Piano Rolls. The sites on the internet I go to says he didn't start making Piano Rolls or Records until 1923, however there is someone insisting under the comments on this site, that he started making records and piano rolls back around the turn of the last Century when he was in his teens. Can anyone shed some light on this conflict ??
