Well, let's see here......you may be too warm for gallicas, but maybe centifolias would work, the oldest of which is Fantin-Latour, dating way back in the 1800s. If you want to go to the trouble of stripping your rosebush of all leaves in the winter, you might use a gallica, the oldest of which is Rosa Mundi, a bi-color pink and white. It dates to the 1500s, and has that camellia-type blossom. This is a fairly small rose, 2.5 feet in height. The other choice is the Apothecary's Rose, but a zone 3 rose, and again, unless you want to take care to strip it every winter, it won't bloom for you as it will for me. The other gallica that might work is Belle Doria.
Except for Belle Doria, all the above roses are in my garden and growing.
I recommend a bourbon, Mme. Cornelissen, which dates to the 1800s, looking very much like a camellia blossom in this picture:

Does this help so far?
