Dear Helen I can't help with much information but can offer the following which I believe relates to the same family.
Kenneth Findlay arrived in Kiambu in 1913. Kiambu is about 10 miles from Nairobi and is a coffee growing area on the lower slopes of the Aberdares. Kenneth had four sons who all served in the First World War, the eldest lost his life in the Dardanelles and the other 3 all received the Military Cross. (You may already know this of course). The 3 sons took over parts of the family estate (Waitangi Estate)after the death of their father and lived in Kiambu all of their lives.
I can give you the following family names
Findlay H CMC Findlay James GMC Findlay Kenneth Jwife Connie Findlay Ronald S Findlay G KMC
