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 by the coincidence of the name of this imaginary character (of supposedly many centuries ago) being the same as yours. The reason of my use of the name is this. I lived near Birmingham as a child, and we used 'gamgee' as a word for 'cotton-wool'; so in my story the families of Cotton and Gamgee are connected. I did not know as a child, though I know now, that 'Gamgee' was shortened from 'gamgee-tissue', and that it was named after its inventor (a surgeon I think) who lived between 1828 and 1886. It was probably his son who died this year, on 1 March, aged 88, after being for many years Professor of Surgery at Birmingham University. Evidently 'Sam' or something like it, is associated with the family – though I never knew this until a few days ago, when I saw Professor Gamgee's obituary notice, and saw that he was son of Sampson Gamgee – and looked in a dictionary and found that the inventor was S. Gamgee (1828-86), & probably the same.
The 'etymology' given in my book is of course quite fictitious, and made up simply for the purposes of my story. I do not suppose you could be bothered to read so long and fantastic a work, especially if you do not care for stories about a mythical world, but if you could be bothered, I know that the work is in most public libraries. It is alas! very expensive to buy. But if you or any of your family try it, and find it interesting enough, I can only say that I shall be happy and proud to send you a signed copy of all 3 vols. as a tribute from the author to the distinguished family of Gamgee.
