Thanks. It's nice to know the name. For the most part I've been very careful to keep a record of the names, but once in a while I slip up. This is one of them.
This particular bulb has heaved up quite a bit and there isn't very much soil left thanks to a couple of mishaps with the cats, so I might look for soil before spring, but maybe not split off the baby right away if it hasn't started to form roots.
