[5] After teaching for a while at Diss Grammar School in Norfolk, she was married in 1922 to Rowland H. Rash (1890–1977), a long-established farmer and landowner in Wortham, Suffolk.

[5] While they raised three children, she taught part-time for the Workers' Educational Association and began a writing career that lasted into the 1980s.

Her moves against the imposition of tithes led to the stock of two farms being impounded in 1935, a siege at Wortham Manor, confrontation with local Blackshirts, and bankruptcy in 1939.

Her first novel, A Little Learning (1931) has a girl with an Oxford degree escaping from her rough farming family into a dull, loveless marriage.
