It has also been reported that the couple decided to name her Louise after Louise of Hesse-Kassel, her paternal great-great-great-grandmother, as well as Queen Victoria’s daughter Princess Louise. Louise of Hesse-Kassel was Queen of Denmark from 1863 to 1898 by virtue of her marriage to King Christian IX of Denmark.
Mary is a nod to the former Princess Royal Mary, Countess of Harewood and Sophie’s mother, Mary Rhys Jones.
The Earl and Countess also opted out of giving their children Prince and Princess titles, instead going for Lady Louise and James, Viscount Severn.
The pair have been kept out of the royal limelight throughout their childhoods, and are usually only seen at major events such as Royal weddings and Trooping the Colour.
