Answer: Based on your description I think these could be a bulb lily (Lilium) of some kind, possibly an Asiatic hybrid or possibly an early season trumpet or Oriental hybrid. The American Lily Society shows photos of several types on their web site to give you an idea of the different flowers these plants produce. There are many different named varieties of each type.
If by tiger lily you mean a daylily (Hemerocallis) with the grassy textured foliage, there are so many yellow varieties it would be difficult to name it. You might try visiting a display garden to see if you can find it or something similar, or perhaps the owner of the display could help you identify it. Here is a listing of the American Hemerocallis Society display gardens.
I hope this helps!
