From the kingdom of Deira; possibly water or oak
Deira was an ancient Anglian kingdom in Northern England during the 6th century. The etymology is debated, likely stemming from the Old Welsh word 'deifr' meaning 'waters' or the Celtic word for 'oak'. It is a rare geographical choice that feels both ancient and modern.
