Sidney Oldall Addy, The Hall of Waltheof — XI. Holy Wells (1893)
“ This well called the Helrin Well or the Olrin Well was at Bradway in the parish of Norton and county of Derby, just outside the boundary of Hallamshire. In mentioning it I feel that I am rather poaching on foreign preserves, but the name is too interesting to be passed by. Grimm observes that the Old Norse name Ölrún belongs to a wise woman. [5] Tacitus mentions a famous German prophetess or sorceress whom he calls Aurinia, and Grimm thinks that the true form of the word may have been Aliruna, or Alioruna. ”
