Zara Phillips is believed to be  setting a royal precedent by not taking the surname of Mike Tindall.  Even when they marry commoners, Royal brides have always adopted the  family name of their partners. When Lady Sarah Armstrong-Jones, daughter  of Princess Margaret and the Earl of Snowdon, wed Daniel Chatto in 1994  she took on his name. Zara's decision appears to be based on the fact  she wants to preserve her sporting persona and business interests. The  former equestrian world champion is known throughout the sport as Zara  Phillips and she has signed a number of deals which help fund her  sporting interests.
