Dennis,

I think that Twain met Oscar Wilde only once, in the late 1880s.  Aafter
Wilde was imprisoned for two years of hard labor in Reading Gaol. in 1895,
he left prison bankrupt in 1895 and moved to the Continent under the name
Sabastian Melmoth. Twain called on the Wildes in London in the late 1880s,
signing Constance's autograph book.  According to CLara Clemens (Twain's
daughter) Twain and Wilde met in a hotel in Bad Nauheim, Germany.  Wilde
wore "a carnation as large as a bqby sumflower" and created great
excitement for the Clemens women.

There may be more of a personal connection, but I am not aware of it.
