On 25 July 1899, at Holy Trinity Church, Sloane Street, Cadogan Square, in London, England, de Meyer married Donna Olga Caracciolo, an Italian noblewoman who had been divorced earlier that year from Nobile Marino Brancaccio; she was a goddaughter of Edward VII [REF].
The de Meyers' marriage was one of marriage of convenience rather than romantic love, since the groom was homosexual and the bride was bisexual or lesbian [REF].
