[4] The illegitimate daughter of banker Alfred de Rothschild, Almina inherited a large fortune that funded her husband's estate and the search for Tutankhamun's tomb in Egypt.

[7][8] On 26 June 1895, aged 19, she married George Edward Stanhope Molyneux Herbert, 5th Earl of Carnarvon at St Margaret's, Westminster.

[12] The Earl of Carnarvon developed an interest in Egyptology and became the financial backer of the search for Tutankhamun's tomb in the Valley of the Kings, Egypt, assisted by Almina's wealth.

Almina saw this as blackmail and persuaded her new husband to contest the claim in the courts, in what Sir Henry McCardie, who tried the case, called "the most bitterly conducted litigation I have ever known".

[19] A courtroom speech by Norman Birkett persuaded the jury to decide to disregard the agreement of Dennistoun to pay ancillary relief to his former wife.

[20] After the death of Lord Carnarvon, Almina was provided with a house in the grounds of Highclere Castle, before she and Colonel Dennistoun moved to the Isle of Wight.
