IS there some local Derby person who can enlighten me please!

Phillimores Volume 4 is entitled “Marriages at St Alkmund’s, Derby”.
And there is an entry for Thomas Harpur who married Margaret Elde 27th August 1736. They are both ‘of Etwall”. However, it says ‘At Quarne’. I can’t find any information about a church at Quarne. Is it now ‘Quarndon’? Their registers don’t start until 1755 evidently, so are we back to looking at St Alkmund’s?
So where would I have to look for the actual entry? All the references on-line are of transcriptions as far as I can see. I have the marriage licence bond and allegation, which has yet another puzzler in it. See this post
http://www.rootschat.com/forum/index.php?topic=750069.msg5980370#msg5980370Can anybody look up marriages at St Alkmund’s in the registers?
Or is my next option is to see if Derbyshire Record Office have the registers?
Thanks for any help.
