From the vocabulary word denoting the evergreen shrub or tree (Middle English holi(n), Old English holegn). The name was first used at the beginning of the 20th century, and has been particularly popular since the 1990s. It is bestowed especially on girls born around Christmas, when sprigs of holly are traditionally taken indoors to decorate rooms.
Polish: 1. from nawrócić ‘to be converted’, hence a name for a religious convert, in particular a Jew who had converted to Christianity. 2. possibly also a habitational name for someone from Nawrotów in Kalisz voivodeship. The name is well established in Germany.
