Keatinge was born in Bombay, India (now
Mumbai), when his father worked for the
Indian Civil Service. His grandfather, Maurice Keatinge (1816–96), had been Principal Registrar Court of Probate, Ireland and his great-grandfather, Rt. Hon.
Richard Keatinge, was Judge of the Prerogative Court of Ireland. (All no doubt connected to
Maurice Keatinge). At the age of five he was sent to England to be educated, later boarding at
Rugby, and then went to South Africa to study at the School of Agriculture in
Natal. He worked for the South African Department of Education until 1929, when he returned to England. and they married in 1930. The honeymoon included a trip up the
Rhine, during which Keatinge became
convinced that another war with Germany was likely. During the next ten years, he divided his time between the
Territorial Army, local activism in the
Conservative Party, and work in Risby on Reginald Burrell's farm. He was particularly adept at the business of military organisation and became an artillery officer in the
Suffolk Yeomanry. In
World War II Keatinge served in the
Royal Artillery. He commanded a mountain battery of the
West African Frontier Force, and became the first commander of the West African Artillery School. When, after a serious illness, he returned to
Suffolk in 1943, he was again attached to the Suffolk Yeomanry, eventually reaching the rank of
lieutenant-colonel. == Member of Parliament ==
