Burgess married Nina Osborne in 1905, but she died in childbirth a year later, leaving him to raise their son alone. It is said that he began writing bedtime stories to entertain his young son, Thornton III. Burgess remarried in 1911; his wife Fannie had two children by a previous marriage. The couple later bought a home in Hampden, Massachusetts in 1925, that became Burgess' permanent residence in 1957. His second wife died in August 1950. Burgess returned frequently to Sandwich, which he always claimed as his birthplace and spiritual home. Many of his childhood experiences and the people he knew there influenced his interest and were the impetus for his concern for wildlife.
