Francis Xavier Morgan
Father Francis Xavier Morgan, forbade Tolkien to see Edith Bratt until he was twenty-one because he saw her as a distraction from his studies. With one exception, Tolkien obeyed this instruction to the letter while Father Morgan's guardianship lasted. After that period he wedded the couple in 1916.
He was the inspiration behind the character Thingol.
Tolkien named his first son, John Francis Reuel after him.
