The three acorns represent Mr. and Mrs. Middleton’s three children (Catherine, Philippa and James). The acorns represent the area where the Middleton children grew up – West Berkshire, England which is surrounded by oak trees. Additionally, oak is a long-established symbol of both ‘England’ and ‘Strength.’
The gold chevron, which sits at the center of the design, represents Mrs. Middleton, whose maiden name is Goldsmith. The two thinner chevrons, which sit either side of the gold chevron, allude to hills and mountains and represent outdoor pursuits that the family enjoy together. The colors blue and red were chosen as they are the principle colors from the flag of the United Kingdom.
