Help with identifying a rose please

Hi, I'v got a beautiful rose in the garden that is sadly starting to look a bit sorry for itself and I'm looking to try and replace it but I really want the same rose again and have no idea what it is. Its got the most stunning citrus scent. I've tried taking cuttings with no luck and was thinking of moving it but I'm frightened the move might finally finish it off. To be honest it's never looked very happy where it is but we've just had a new shed built so it's in lots of shade and looks like it's all but dies except for a sucker. Below are images of the rose i took last year, it was sadly one of only three flowers it produced. 

I would not try to move an established rose.

The roots of roses do not form a compact root ball that you can easily dig up.  The roots are normally long and wiry. They can extend for several feet. You would almost certainly sever them.

The sucker will come from a different variety of rose, and although it may ultimately flower, it will not be the same flower as the one you have.

I'm not an expert on rose varieties, but Peter Beales has a very clever website which enables you to select roses by any number of attributes.

So, for example, you can find all his roses which are both yellow and scented:
Peter Beales Yellow Scented Roses

Though your rose could be one that is not sold by him. Graham Thomas (a David Austin rose) looks a tiny bit like yours (but I'm not sure about the scent).

Perhaps others might have some better ideas...

Thank you for the link to the website, Arthur Bell looks similar but I've dropped them a e-mail with the same images to see if it might be Arthur Bell and if they have any other ideas what it might be. 

I have a nice rose 'Chatterbox' that must be at least 30 years old which was on it's last legs two years ago - I dug it up, put it in a pot in the greenhouse and eventually new shoots appeared !  Now it is back and thriving in the garden. So if you really can't find out the name of your rose doing this might be worth a try.  Good luck.

Roses really don't enjoy shade although a few tolerate it and they certainly can be moved, but preferably in the dormant period, late autumn to early spring. True the roots don't form a nice closely knitted mass like some plants but after all that's what bare rooted roses are. As I recommended in another Rose I/D thread, the Peter Beales website is a good start, or go along to your local garden centre and smell an 'Arthur Bell', a gorgeous yellow scented rose. I came across one only last weekend.
