Has anyone an idea where to get

the Henry Ford rose? I looked on the internet and the only place responding was asking the same question. Mine is about 20 years old and seems to give up its ghost. Another question: can one rejuvinate an old rose? I have 3 The Fairy roses and they seem to struggle as well. Of course, those I could replace. The grass grows right into the root system; that is why I would like to know how far one can cut into older stems to rescue the plant.
