… he claimed to be genuinely surprised when, in March 1956, he received a letter from one Sam Gamgee, who had heard that his name was in The Lord of the Rings but had not read the book. Tolkien replied on March 18:

Dear Mr. Gamgee,

It was very kind of you to write. You can imagine my astonishment when I saw your signature! I can only say, for your comfort, I hope, that the ‘Sam Gamgee’ of my story is a most heroic character, now widely beloved by many readers, even though his origins are rustic. So that perhaps you will not be displeased at the coincidence of the name of this imaginary character of supposedly many centuries ago being the same as yours.

He proceeded to send Mr Gamgee a signed copy of all three volumes of the book. However, the incident sparked a nagging worry in Tolkien’s mind, as he recorded in his journal:

For some time I lived in fear of receiving a letter signed ’S. Gollum’. That would have been more difficult to deal with.“― J.R.R. Tolkien: A Biography
