With the greatest respect. You are on a wild goose chase. I've been growing roses here in the UK for seventy years. I would never attempt to identify a rose under normal circumstances. So much needs to be known. OK. A name might be suggested, and you could easily accept that. You say the rose has died. Try this. Trace the stem/s back to close to ground level. Peel back a small portion of the bark. Is this dead or is it still green. If green, that's an indication the roots are alive. If brown then the stem is dead. However not all is lost. Cut back all dead wood to about a foot above ground level. Mulch the root-stock and keep watered. You may be lucky and get some new growth. Best wishes.
