Yes I live in Adelaide. I am descended from Job Usher and Eliza Axford. I know that Henry Usher and Hannah Axford are closely related to them probably brothers and sisters. The name Fairley is used in one of their childrens names but is a mystery to me.
I know about their families in Adelaide but I don't have much else for Wiltshire info . If you come across their names in your research could you let me know and I'll keep a lookout for your Axfords too.
