Swayback,
I meant to tell you before, I am so sorry you are losing a rose that has been in your family for so long. That's quite an accomplishment.
If the disease has not yet spread to one of the roses, maybe you could start cuttings? Keep in mind, though, that the disease is often in the rose before it shows symptoms. I'm sentimental about "family" roses, and hate to see you lose this one entirely, so I'm looking at a long shot here.
Any that do have the disease need to be removed, pronto. Disenfect your pruners or loppers after working on them. Don't plant another rose in that spot for a few years, until you are positive there are no root pieces remaining in the soil.
So sorry you lost the living heirlooms.
