da Cunha married Ana Emília Ribeiro, daughter of major Sólon Ribeiro, in 1890. The couple had five children. Ana Emília had an affair with Dilermando de Assis, a young Army lieutenant. On August 15, 1909, finding about his wife's affair, da Cunha went to Assis' house to kill him. He shot Assis and his brother Dinorah, failing to kill either. Assis shot da Cunha when Euclides had already left his house, and the writer was killed. According to historian Susanna Hecht's account, there was doubt whether Dilermando murdered a fleeing man who had run out of bullets, or whether Euclides still was a threat to Dilermando (which would make the murder self-defense.) The jury decided for the latter scenario and acquitted Dilermando. Da Cunha was 43 years old.
