In 1892 Robert Louis Stevenson invited Barrie to Samoa. 
He invited him again in 1893. 
J.M.Barrie and his friend, fellow Scots writer S.R.Crockett considered going in the spring of 1894. But Barrie got sick and Crockett got famous. And Barrie got married and Crockett got more famous... and then Stevenson died.

John Donne said 'No man is an island.'  Barrie disagreed. Islands feature in much of Barrie's work and we might even say he developed a 'Theory of Islands'.  If you want an introduction into this, why not check out Barrie's own 1894 article 'Wrecked on an Island'  and Cally Phillips' 2018 conference paper 'Islands and Identity'
