On Bonanza, surprisngly

Or maybe not. She also had a very nice turn on Gunsmoke playing mostly across from Milburn Stone as a female physician.
Here on Bonanza I didn't recognize her at first, but as soon as I saw the name I thought, I'm definitely watching this. As the one other post says -- stunningly beautiful, especially in the Grace Kelly vein, and a wonderful actress, easily convincing on screen.
