For 1999 season, the Arizona Diamondbacks had eight minor league affiliates.  There were two triple-A affiliates including one based in the Mexican League.  This was the first season the Diamondbacks fielded a Double-A team.  The Pioneer League team moved from Lethbridge to Missoula Montana for the 1999 season.  The two lower level affiliates are no longer in business and therefore have no contact information.
