309 From a letter to Amy Ronald 2
January 1969

Now, my dear, as to my name. It is John: a name much used and loved by Christians, and since I was born on the Octave of St John the Evangelist, I take him as my patron – though neither my father, nor my mother at that time, would have thought of anything so Romish as giving me a name because it was a saint's. I was called John because it was the custom for the eldest son of the eldest son to be called John in my family. My father was Arthur, eldest of my grandfather John Benjamin's second family; but his elder half-brother John had died leaving only 3 daughters. So John I had to be, and was dandled on the knee of old J.B., as the heir, before he died. (I was only four when he died at 92 in 1896.)1
My father favoured John Benjamin Reuel (which I should now have liked); but my mother was confident that I should be a daughter, and being fond of more 'romantic' (& less O[ld] T[estament] like) names decided on Rosalind. When I turned up, prematurely, and a boy though weak and ailing, Ronald was substituted. It was then a much rarer name in England as a Christian name – I never in fact knew any of my contemporaries at school or Oxford who had the name – though it seems now alas! to be prevalent among the criminal and other degraded classes. Anyway I have always treated it with respect, and from earliest days refused to allow it to be abbreviated or tagged with. But for myself I remained John. Ronald was for my near kin. My friends at school, Oxford and later have called me John (or occasionally John Ronald or J. Rsquared).....2
As for an 'Elvish' name: I could of course invent one. But I do not really belong inside my invented history; and do not wish to!
As for Master: I am not one. In high uses it would be presumptuous and profane to adopt such a title; in lower uses it is conceited. I am a 'professor' — or was, and occasionally in more inspired moments deserved the title – and it is now at any rate (though not in Oxford of the generation before mine) a customary social title.
So what? I think if for private reasons John or Ronald is not pleasing for you to use (I quite understand that the collocation John Ronald is so) then we must fall back on 'Professor'. (And I shall call you Lady!)
Of course there is always Reuel. This was (I believe) the surname of a friend of my grandfather. The family believed it to be French (which is formally possible); but if so it is an odd chance that it appears twice in the O[ld] T[estament] as an unexplained other name for Jethro Moses' father-in-law. All my children, and my children's children, and their children, have the name.
I think I shall call you Aimée, which I like better than its anglicization, and suits your love & knowledge of French. ....
