What are the first and last names of a Shaw character?

Question

The total number of letters in both names is 13 and
5 of the letters in his name spell BILBO.
He was adopted by a policeman's wife and became
president of the board of trade.

Answer 1

That would be Bill Boanerges in "The Apple Cart". Actually quite a terrific play--saw a good production in London a number of years ago which sold me on the play as a forgotten classic. I think it would play very well nowadays, given the state of the British monarchy and the relationship between the UK and USA....

Answer 2

Balbo Baggins?
Bilbo Baggins?
Bingo Baggins?
Bungo Baggins?
