The Burghers were legally defined by law in 1883, by the Chief Justice of Ceylon, Sir Richard Ottley, given before the Commission which was appointed in connection with the establishment of a legislative Council in Ceylon. It was decided that in order to be defined as a Burgher, one's father had to have been born in Sri Lanka, with at least one European ancestor on one's direct paternal side, regardless of the ethnic origin of one's mother, or what other ethnic groups may be found on the father's side. Because of this definition, Burghers almost always have European surnames (mostly of Portuguese, Dutch and British origin, although it is not uncommon to also find German, French or Russian surnames).
