Since her engagement to Prince Harry in November, Meghan has held meetings with Cohen for briefings about the Commonwealth and the workings of the monarchy - all likely quite unfamiliar for the American-born Duchess.
Yesterday was Meghan Markle's first official appearance as the Duchess of Sussex, and her royal influence is already clear to see.
The blue background of the shield represents the Pacific Ocean off the California coast, while two golden rays across the shield are symbolic of the sunshine of Meghan's hometown of Los Angeles.
Other personal touches include wintersweet, which grows at Kensington Palace, where she now lives with Harry.
The Duchess of Sussex made sure to incorporate elements of her home state while highlighting the power of communication.
Meghan officially became part of the royal family after her May 19 wedding to Prince Harry.
Three quills represent the power of words and communication.
Officials said Meghan, who Wednesday Prince Harry on May 19 in a spectacular ceremony at Windsor Castle, worked closely with the College of Arms in London to create the design.
Meghan's coat of arms was created for her, not her family, because she is not yet a British citizen.
It is customary for wives of members of the royal family to have one of their husband's supporters of the shield and one relating to themselves.
They were granted the titles Duke and Duchess of Sussex on the day of the wedding; they are also the Earl and Countess of Dumbarton and the Baron and Baroness of Kilkeel.
Before Prince William and Princess Kate were married in 2011, Kate was granted a coat of arms that represented the history and interests of her parents and two siblings. People said the design will likely be unveiled in a couple years. The Supporter on the left, the lion, is also one of Prince Harry's Supporters on his coat of arms.
