Harold Dold and Arthur Clifford HILL were cousins and were ostich farmers in the Machakos district. They later became involved with game hunting.
<< Clifford and Harold Hill were ostrich farmers whose birds were plagued by lions. They decided to invite hunters in to shoot the lions, charging a fee for this. Visiting hunters turned up in droves: the safari business had begun.>> SOURCE: http://www.safariconsultant.com/history2.htmhttp://www.safariconsultant.com/history2.htm
You mentioned that the "Permanent Way" was written by M.F. Hill (1949). I am trying to locate any snippets on this family.
