Adelaide is a name of German origin, derived from the elements 'adal' meaning noble and 'heid' meaning kind, bright. It was introduced to England by the Normans and has been used steadily since then, though it gained significant popularity during the Victorian era. The name Adelaide is often associated with elegance and sophistication, perhaps due to its historical use among royalty.
"Adelade saw peaks in popularity with 13 babies named in 2008 and again in 2015 with 8 names, but the name has since declined, averaging around 5 births per year from 2014 to 2021."
