Cousin Louie

Princess Marie Louise of Schleswig-Holstein (12th August 1872 - 8th December 1956), a granddaughter of Queen Victoria, photographed by Cecil Beaton.

According to Angus Trumble, writing in The Paris Review:

“Cousin Louie,” as she was known, was the fourth child of Queen Victoria’s bad-tempered middle daughter, Princess Helena. Her book My Memories of Six Reigns is a fantastically weird combination of out-of-sequence table-rapping reminiscence; reverent reflection upon the burdens of monarchy, and innumerable flecks of interesting detail.

Louie’s Edwardian wedding to Prince Aribert of Anhalt was the bright idea of Cousin Willie, the Kaiser, but more accurately an example of his total lack of judgment. It seems the Prince was soon afterwards caught in flagrante with an attractive young male servant in, on, or more probably beside the marital bed, and, concluding from this that her marriage was no longer viable, Louie promptly undertook an extended tour of Canada and the United States. Returning to Britain she immersed herself in charitable and artistic work, set up a Girls’ Club in Bermondsey, kept an eye on her mother’s nursing homes, and lent modest support to the imperial trade in dried fruit. Wholly guileless, Princess Marie Louise is irresistible.
