OUCHTERLONY, John. Walworth, Surrey 15.1.1813 — Ootacamund 29.4.1863. British Colonial Officer in India. Lieutenant-Colonel. Son of William O. and Harriet Lee. Served in Madras Engineers, in 1741-43 in Hong Kong. Married 1844 Alice Trevor Puchterbury (anc.) or Turton (Wikitree), four daughters. Died of “jungle fever”. His identification as the author of the three books was first tentative, but seems very likely. There are at least two other men of the same name in India around the mid-19th century, but they seem to be out of questions.
