This was the name of a 13th-century Italian saint who made clothes for the poor. As an English name, it has never been common.
In the English-speaking world this name has been occasionally given since the early 20th century. It started rising in America after the variant Lorelai was used for the main character (and her daughter, nicknamed Rory) on the television series Gilmore Girls (2000-2007).
This name was not regularly given to people until the 19th century [4][3]. It was used by George Eliot for a character in her novel Daniel Deronda (1876).
