James I dont have the book with me now.

All I can remember is that it is called "The Diamond King", by Brian Mylchreest.

It tells of the story of Joseph Mylchreest's mining adventures around the world and esp South Africa and his return to Peel with his wife and family to retire abt 1890 I think.Mentions also other Manxmen going to Kimberly mines to work the diamonds too. Also the family genealogy in fair detail is included of course. I think the book was written about 1993/4

Hope this helps.
