It may seem strange, but I will begin answering that question by looking at William Shakespeare. For decades scholars argued about who Shakespeare really was. Some insisted that Christopher Marlow was the true author of the plays. The Earl of Oxford was another. In recent years more and more evidence shows that, in fact, Shakespeare was Shakespeare.
He was the son of John Shakespeare, a recusant who kept the faith, a local low-level politician who resigned his office rather than take the oath of supremacy. His son William's missing years were probably spent being educated on the continent which explains his broad knowledge of Italy, particularly Venice. Another indication of his Catholicism was his ownership of a house in London used for secret Masses. It was exposed when a floor collapsed under the weight of several hundred Catholics hearing the Mass. [Brief article on Shakespeare's Catholicism.]
