What is hardy wife?

There isn't a specific "Hardy wife" that I am aware of. However, Thomas Hardy, the English novelist and poet, was married twice. His first wife was Emma Gifford, whom he married in 1874. They had a tumultuous relationship, and Emma's passing in 1912 deeply affected Hardy. He later remarried to Florence Dugdale in 1914, after Emma's death. Hardy's relationships with both his wives have been subjects of interest for literary scholars and biographers.
