Hi, Miranda,
Unfortunately I haven't identified this vicar yet, but you are just the kind of visitor I hope to read my post, as I do the very same thing now and then, idly browsing forums for extremely long shots just in case something turns up.
The thought remains that someone else might have an old wedding photograph featuring this vicar but with his name on the back!
A shame that Crockford's Clerical Directory didn't include portraits of each cleric.
I sometimes wonder if the 1930's were further back in time than ancient Egypt for the difficulties involved in identifying these people.
A George Hayden (Rector) married my grandparents in 1912 at St Clements, Longsight, would this then have been your grandfather?
