Hi wyldathart,

If you want to search on-line, you could try this -

http://www.royal.gov.uk/TheRoyalHousehold/Overview.aspx

and from Wikipedia, search -

Royal Households of the United Kingdom

You might also want to search for 'Royal Warrant Holders'. These are people, or businesses, who supply goods or a service to members of the Royal Family.

Regards
