Formation of Croatian family names based on female first names wasn’t a frequent occurence and is often difficult to discern that a surname is actually motivated by the first name of a woman.
Earlier in history, women would typically not bear a surname, but would use the name of a father, husband, brother or a son instead. A matronymic surname would be typically created using a name of a women who particularly excelled in a community, or was famous because of some fortunate or less fortunate circumstance like becoming a widow early in life or being pregnant out of wedlock.
