Polymath 1000

[Ameld]

Hello. I think I am going slightly mad! A particular clue is the cause.
It is in the Weekend FT Polymath. The clue is
"A non-dictionary word overlapping "Peter" in Spanish with a name Jesus gave to Peter"
With the letters I have the answer could well be "pedrock". Pedro is Spanish for Peter and Jesus called Peter a rock. So, overlapping them gives me pedrock. But what on earth does it mean? I suppose it could be a "non dictionary word". But is it even a word? Not according to my dictionary. But ,as it is a non dictionary word, of course it is not in my dictionary. And so the confusion in my brain swirls round and round. Could someone who knows about these things (remember I am quite new still to crosswords) please help me. Please!

Pedrock is an FT Setter - as in the mini theme.

Peter CHAMBERLAIN
Peter Chamberlain, a former accountant, has been a crossword setter for The Daily Telegraph since 1986. He regularly sets the Saturday prize cryptic in that paper and he also sets Toughie crosswords as Cephas.

As Pedrock he sets Polymath crosswords in the Financial Times and crosswords in 1 Across.

Oh thank you, Mamyalynne. I'm not experienced enough to know the names of the setters. But now you have pointed this out, I see that Armonie (which I got by a more normal route) is another setter and, no doubt others are there too. But I don't know which.
Given that it is No 1000 I expected some twists but that one is a bit above my pay grade. Now I can rest.
I am so grateful. As I said it was driving me bonkers.
In case I don't get another chance can I wish you (and the many other helpers on this most generous of sites) a Very Happy Christmas. May it be peaceful for us all

It was the one I struggled with most Alan and I do know Pedrock,so should have found it easily.

I wish you and yours a wonderful Christmas too.x
