Thornewaite

Jane's last name in the headline - of "Thornewaite faces drunk driving charge" in 24H Vancouver on February 24, 2010 - and in the photo caption is Thornewaite. Her last name in the article's only mention is Thornthwaite. To recap: twice it's Thornewaite, once it's Thornthwaite. Which do you think is correct? I went with the majority and thought Thornewaite. I was wrong. Here's the proof.
