After her marriage to Lovecraft ended, in 1933 Greene moved to California. In 1936, she married a Dr Nathaniel Abraham Davis of Los Angeles. She did not hear of Lovecraft's death until eight years later, in 1945. Her marriage to Lovecraft was never legally ended because Lovecraft, although he assured her the divorce had been filed, failed to sign the final decree, so Greene's union with Davis was technically bigamous. Greene was informed of this late in life and it disturbed her considerably. Her husband Nathaniel Davis died in 1946.
