Madaleno is of Portuguese origin, derived from the word 'madalena', which means 'magdalen'. It is a unisex name, traditionally given to both boys and girls, though it is more commonly used for males today. The name gained popularity due to its association with Mary Magdalene, one of Jesus Christ's followers in Christian tradition.
The name Madaleno had a single peak year of popularity with 6 births in 1953, but it has not gained significant traction since then, remaining relatively rare with no further births recorded in subsequent years.
