Aul is of Germanic origin, derived from the Old Norse element 'álr', which means 'swamp'. It is a rare yet distinctive name that evokes images of nature and its untamed beauty. In some cases, it may also be associated with the Irish surname 'O'Connell', though it is not commonly used as a given name.
The name Aul experienced a notable increase in popularity between 1984 and 1985, with the number of births doubling from 8 to 16 during those two years. This surge accounted for nearly one-third of all Aul births recorded between 1968 and 1985, which totaled 46 in that period.
