There are probably more. Back in the 70's, AIS didn't list the hybridizer's first name, just the initial. Dave fixed many of those for us, but I don't think Mrs. Miller was among them. If you search for B. Miller in the database (how did you get the search results to show in your link, Dave, I can never get that to work?), there are another 47 irises that all appear to be hers.
