I heard that Michael Landon picked Karen Grassle out specifically for her "pioneer" looks, and I would say he was right in choosing her. She definitely fit the part.

Like any good mother, Caroline was the heart and moral cmpass for her family. It was her belief in her husband that allowed him to be the man he was. She was a modest beauty that would defend her family like a lioness protecting her cubs, whenever they were threatened.

I wish I was half the woman Caroline Engalls was

I would have to say she probably is one of the best TV mothers. A good example for her daughters to follow in her footsteps and grow up to be decent ladies.
