Articles with proper names

I have noticed that there are sometimes articles before proper names (such as, A Brittany). If you're writing a sentence in Portuguese and the subject is a proper noun, do you use an article? Por exemplo: A Brittany é uma professora. Brittany é uma professora. Which is correct? Thank you!

Hi Brittany, Both are correct, but usually people tend to say with an article and write without. Hope this helps, Cheers :)

Hi, so in speaking we can use the article but in writing we can just use the name? Obrigada!

Hi Brittany, Yes, in writing we don't use articles. Cheers, Tereza.
