What Wilbury pseudonym did Harrison use on 'Traveling Wilburys Vol. 1'?

George Harrison used the Wilbury pseudonym Nelson Wilbury on Traveling Wilburys Vol. 1.

The 1988 album presented its five famous musicians as fictional half-brothers rather than using their real names. Harrison was Nelson Wilbury; Jeff Lynne was Otis, Bob Dylan was Lucky, Roy Orbison was Lefty, and Tom Petty was Charlie T. Wilbury Jr. Harrison and Lynne were also credited as the album's producers under their Wilbury identities.

The group began almost accidentally when Harrison, Lynne, Orbison, Dylan and Petty recorded “Handle with Care” as a proposed B-side. The track seemed too strong for that purpose, so the musicians recorded a full album in 1988. Traveling Wilburys Vol. 1 was released on 18 October and became a major critical and commercial success.

A frequent mix-up is Spike Wilbury, another Harrison alias used on Traveling Wilburys Vol. 3. Lefty Wilbury belonged to Orbison, while Charlie T. Wilbury Jr. belonged to Petty, making the answer specific to Harrison's credited character on the first album.
