King James II was the son of Charles I
and the last Catholic monarch of England, Scotland, and Ireland. His conversion to Catholicism affected many of his decisions as king. He was eventually forced into exile by his own daughter, Mary, and her Protestant husband, William of Orange, as opponents feared the growing strength of Catholicism in the country. And of course, James is the name of two Apostles in the New Testament. So a baby James Sussex would be in great company!
