Dolly replaced Diana in 1996, so this is the 6th season with the name on the list. In previous years there was a Cat 2, a Cat 1 and three tropical storms.
I think they have a rotation of six lists; if a particular name is retired, it gets replaced; and if the season exceeds the standard 21 names for a year, supplementary names are added.
(I’m proud to be one of the ‘retired’ names :-)
Found some more on Wikipedia from other regions and before 1996.
