In the past (before 20th century), when parents baptismed their daughter with 'Maria' as a given name, the priests in the parish book had used to write not 'Maria', but 'Marianna' as her given name. Therefore, the person was called Marianna in all church issues, and usually also in all civil issues. Forename 'Maria' was reserved for Maria from the Nazareth, the Mother of Jesus Christ.
