Ernest Luscombe Penery would have arrived in South Africa in 1900/01 where he served in the Royal Army Medical Corps in the Cape Colony during the Anglo Boer War. I have hi Queens South Africa Medal with date clasps 1901 - 1902.
He seemed to move from the Cape to the Transvaal (children born there) and then Durban (children born there). Children also born in Pietermaritzburg in 1922.
I did find a listing in 1922 in now Mozambique for a British birth for a Ernest Luscombe Penery, i think this should have been "death" and not "birth". After this he disappears from record.
