By December 1909, Natalia was pregnant. Fearful that her husband would try to claim the child and take it away from her, her desire for a divorce grew stronger. Eventually, after prolonged negotiations and a hefty pay-off, Wulfert agreed to a divorce on the pretence that he had been unfaithful. Natalia's divorce petition was submitted to the Moscow Ecclesiastical Consistory Court on 19 February 1910, but by July 1910 it had not been granted. When she gave birth to a son on 24 July 1910, the child was legally Wulfert's. The boy was named George in honour of Michael's late brother. It was said that Wulfert was bought off with a bribe of 200,000 roubles, and the date of their divorce was back-dated, so that George was recognised as Natalia's illegitimate son, though inheriting her noble status, rather than the legitimate child of Wulfert's.
