Ustinov was born Jonah Freiherr[1] von Ustinow in Jaffa, Palestine, then part of the Ottoman Empire, the son of Plato von Ustinov, a former Russian officer and naturalised citizen of the Kingdom of Württemberg, who had married Magdalena Hall, then living in Jaffa, the daughter of the Ethiopian court-lady Katharina Hall, also known as Welette-Iyesus and her husband Moritz Hall, a Jewish-born convert to Protestantism, cannon-caster of Negus Tewodros II of Ethiopia and missionary of St. Chrischona Pilgrim Mission in Ethiopia, and later in Jaffa.[2]
Magdalena and Plato von Ustinov had four children, Jonah being the eldest.[3]
Jonah von Ustinov disliked his first name and chose the nickname "Klop" ("Bedbug" in Russian), by which he was known to his friends and relatives for the rest of his life.
He is "unique" in having performed service in the Russian, German and British armies...
