What Was The Surname Of Wendy And Her Brothers In Peter Pan?

Peter Pan was a fictional character created by a Scottish author called J. M. Barrie who was born in 1860 and died in 1937. The story tells of a mischievous little boy who refuses point blank to grow up into a man. Peter spends his time in never-ending childhood adventures on the small island of Tampa and is the leader of his gang The Lost Boys. It is claimed that Pan is based on a child that Barrie knew.
I the book, Peter goes to the real world and visits London where he meats a young girl and her brothers ~ Wendy, John and Michael Darling. Peter asks Wendy if she will come to Neverland and be a mother to his gang of Lost boys, because she always tells her brothers such lovely bed time stories. Wendy agrees and many adventures ensure.
I the novel Barrie includes a scene which is not in the play, but which he wrote for the stage under the title An Afterthought. In the scene peter returns to Wendy's house to find that 20 years has passed and that she is now a married woman with a daughter. His cries wake Wendy's daughter Jane and Peter persuades her to join him and become his mother, like her mother did. Jane accepts and the adventure begins again. Film producers soon thought that this idea would make an ideal second film and so created Peter Pan part two.

I think it was Darling but cant be sure?
