Thomas Gilcrease Sr. and Norma (Smallwood) Gilcrease were the parents of one daughter, Des Cygne Lamour Gilcrease. She was born on June 12, 1929, in Tulsa, Oklahoma. Thomas Gilcrease, Sr. filed for divorce in October, 1933, for extreme cruelty and gross neglect of duty. He alleged that the couple had been happily married for two years, until Norma's mother, Mahala Dickerson had moved into the house with them and alienated the affections of both Norma and the couple's daughter. He wanted the mother-in-law removed from the property. The Gilcrease-Smallwood marriage ended in divorce on May 2, 1934. Initially, the divorce provided for $72,000 alimony, payable at the rate of $200 per month, but with a provision that all payments would cease if Norma were to remarry. Norma balked at the provision against remarriage, so the court set alimony at $15,000, to be paid at $250 per month.
