I'm only going to reproduce here the names of famous Mormons that stood out to me. I'm quite a nerd, so I didn't recognize half the Mormon TV personalities, actors, punk rockers, etc., even though they may be well-known. I highly recommend the site Famous Mormon, from which I got most of this information and which is far more complete.

When the U.S. declared war on Mexico, Ide and the others joined the U.S. forces thus ending California's independence.” Ide may be the only Mormon head of state in history, unless rumors about the King of Tonga (or is it Samoa?) are true...
- There are currently eight Mormon senators...kind of. Five U.S. senators, one Mexican senator (his great, great grandfather was the first Mormon missionary in Mexico), the delegate to the U.S. Congress from American Samoa (if Samoa were a state, he'd be a senator), and a member of the British parliament. The “senators” come from Utah, Nevada, Oregon, Idaho, American Samoa, Chihuahua state, and England.
