Hi Steven,
Looks like I need to go through a few security hoops before I can send personal messages.
I don't have much direct knowledge of my uncle's time in Kenya, only the stories that I learnt from my Mum and her brothers and sisters. He did lead an interesting life out there, working for one of the major oil companies (Shell or BP, can't quite recall) but can probably find out.
His father (my grandfather) was also called Alfred Ewart Holley and was the manager at Llandarcy oil refinery during the 1930s.
Must go now - but I think one more forum message in your general direction will allow me to contact you directly where we can pick it up in more depth.
What is your interest in my uncle I was wondering?
Best wishes,
Simon
