Doesn't look like an Allium/ onion. Possibly Ornithogalum sp. http://en.wikipedia.org/wiki/Ornithogalum
Your welcome bigace. It's one of my favorite houseplants because not many people have it. I like it when the little pregnant bumps form on the sides. grow then split and the "baby" pops out. Some people don't like the oniony smell it emits ,but I don't mind. ;))))
