What is the first name of the founder of Ravenclaw House?

According to Harry Potter's creator, J.K. Rowling, Rowena Ravenclaw was "the most brilliant witch of her time." She may have been a slightly less-gifted mother, however, as she frequently clashed with her daughter, Helena, who ultimately stole her mother's cherished diadem. Voldemort later turned the stolen headwear into a Horcrux. Whoops.
