Prince Philip nicknamed Meghan Markle 'DoW' due to her perceived similarities to Wallis Simpson, according to royal authors. The Duke of Edinburgh expressed concerns about Meghan's resemblance to the American divorcee, leading the late Queen Elizabeth II to have mixed feelings towards her. Meghan's remarkable attributes were acknowledged by King Charles, who allegedly nicknamed her 'Tungsten' for her toughness and resilience. Queen Elizabeth II supported Meghan despite her strained relationship with her father, Thomas Markle, before her wedding to Prince Harry.
