It has been in common use in Christian countries since the Middle Ages.
Latinate forms of the name in use by 1381 included Sibilla and Sibilia.
It was thought suitable as a name for girls by Christians, despite its pagan origins, because the sibyls had delivered messages from a deity and were thought to have been blessed by God with partial understanding of the coming of Jesus Christ.
Usage of the name recently increased due to a character on the popular TV series Downton Abbey.
[5][6][7] Sibylle, a French version of the name, is considered a bon chic bon genre name more likely to be given to girls from upper class French families.
