Who are Alice's friends in Alice in Wonderland?

In the original book, Alice is described as having one friend, the Cheshire Cat:

Who ARE you talking to?' said the King, going up to Alice, and looking at the Cat's head with great curiOSity.

It's a friend of mine--a Cheshire Cat,' said Alice: allow me to introduce it.'

There is no reference in either of the Alice books to Alice having any real-world friends. In Alice's Adventures in Wonderland, Alice thinks about two children she knows who are the same age as she is, but she doesn't seem to think of them in an especially friendly way. Their names are Ada and Mabel.

....she began thinking over all the children she knew that were of the same age as herself, to see if she could have been changed for any of them.

I'm sure I'm not Ada,' she said, for her hair goes in such long ringlets, and mine doesn't go in ringlets at all; and I'm sure I can't be Mabel, for I know all sorts of things, and she, oh! she knows such a very little!
