Are the characters mentioned in the song "Mack the Knife" based on real people?

The song is from the German "The Threepenny Opera" and refers to MacHeath (or Mackie Messer), who was a violent pimp. Jenny Diver. Lucy Brown and Suky Tawdry are other characters in the opera, all prostitutes. Lotte Lenya was in reality the wife of the composer of the opera, Kurt Weill and her name was attached to a character in an off-Broadway production. Louie Miller represents a would-be client of one of the prostitutes, who is murdered by MacHeath after drawing out money.

Die Dreigroschenoper is a reworking of a much earlier work, The Beggar's Opera, by John Gay (which ran for 62 performances when first launched in 1728, and when revived in 1920 for 1,463 more...). The character of Mack was 'Captain' Macheath - a highwayman (amongst other things...) Jenny Diver and Sukey Tawdry come from Gay's work originally. Lucy Brown, daughter of a police chief in Brecht's play (set to music by Weill), is Lucy Lockit in Gay, daughter of the man running Newgate prison. These were probably based on real-life 'working girls' of the day - but it's unlikely that any solid identification could be made now. (Quite a few of the characters are satirical depictions of real people - the sequel 'Polly' was even worse and got banned for a long time.)
