Walter married around this time and started a family. Unfortunately, Walter suffered from mental illness beginning in 1937, which strained his marriage and family life. But the family moved to Oldfields in 1940 and it was here that Walter created many of his works. His children's imagination and love for fairy tales inspired him greatly at this time. They moved back to Ocean Springs in 1947 but by this time Walter and his wife separated (though they stayed married). Walter built his cottage and started spending more and more time alone in his little room and exploring the natural surroundings. He died in 1965 of lung cancer.
