gosh, lots of questions & suggestions - thank you so much !!
It is a painting, I think it's oil - definitely not watercolour. about 3ft x 2ft. no frame.
it says Dearden on the back in pencil, I never thought it could be a place name. Bartholomew's 1905 gazetteer lists no place called Dearden, and I think (don't have it in front of me) that there IS an initial letter in front of the name. I will check when I get home.
Thanks for the Harold Dearden comment - my plan was to identify the painting and then put it on ebay with the place name found, as the painting is meaningless to me. If it is by a known artist, so much the better.
I have looked on google for photos of the places people have suggested so far, and as you all say, the funny shaped rock on the top is pretty definitive. Nell suggests an amalgamation of places, which I agree is a good idea, but surely if you were painting somewhere "pretty" from imagination, you wouldn't have put that lump on the top would you ? I guess the painting may be an unfinished work, but then it wouldn't have been in my family (sheffield area) unless someone had bought it (or been given it) at some point.
If anyone can pinpoint a photo which looks like this painting, (and if it was a definite single place then it would surely have been photographed!) then I will consider the matter solved. so far there is nothing online which looks like this - even bearing in mind it's probably 100 yeasr ago when it was painted - although I think the recent suggestion of Cornwall coves will bear fruit in the end. Lamorna \Cove looks the closest so far. I might stick this on the Cornwall board too, when the suggestions here dry up !
many thanks

ps, Nell, the geograph link is broken on my pc I'm afraid.
