In the English-speaking world the form Christine was more popular for most of the 20th century, though Christina eventually overtook it. Famous bearers include actress Christina Ricci (1980-) and singer Christina Aguilera (1980-).
The spelling was later altered to Cordelia when Geoffrey's story was adapted by others, including Edmund Spenser in his poem The Faerie Queene (1590) and Shakespeare in his tragedy King Lear (1606).
A famous bearer of the surname was James Madison (1751-1836), one of the authors of the American constitution who later served as president (and after whom Madison Avenue was named).
