Astley is an uncommon given name of English origin, derived from a surname that was derived from Old English elements meaning "from the ash tree ley". It is believed to have been brought to England by Norman invaders in the 11th century. The name Astley gained some popularity during the Victorian era and has since been used occasionally as a given name, but it remains relatively rare today.
"Astley is quite rare; only five babies were named Astley in 1993."
