hello
i had a wee look and you are spot on with everything you say. it does appear that there are many companies using the julius thuvi name.
i have a suggestion, why don't you go to http://www.tourism.go.ke/ministry.nsf/pages/contact_us#
kenya's official ministry of tourism site and contact them asap with your thoughts and see what they say. as they are the countries official tourist site they should shed some light on what is the official one.
i have already saw 2 sites with the juliius name.
