What a shame. Ignoring your second post which is not relevant to the question, your answer is not quite correct, but so close I cannot leave the question outstanding.
The famous person who started the company was the Jockey Dick Francis who was Merrick's Father. Although having a Royal Warrant, the Company has no other connection to HM the Queen, although Dick was said to be the Queen Mother's favourite jockey.
The Main Driver is my own Daughter who has been a driver for the Company for a number of years.
