Offices, and the Council Chamber where Island Council meetings are held. Policing is undertaken by one full-time police inspector and three special constables. Tristan da Cunha has some legislation of its own, but the law of Saint Helena applies generally to the extent that it is not inconsistent with local law, insofar as it is suitable for local circumstances and subject to such modifications as local circumstances make necessary. Chief Islander The Island Council is made up of eight elected and three appointed members, who serve a three-year term which begins in February or March. A separate but simultaneous vote is held to select the Chief Islander, who is the community's political leader. James Glass was re-elected to the position in March 2022 to a record-breaking fifth term in the role. Demographics Tristan da Cunha recorded a population of 243 in the June 2021 census. The only settlement is Edinburgh of the Seven Seas (known locally as "The Settlement"). The current residents are thought to have descended from fifteen outside ancestors, eight male and seven female, who arrived on the island at various dates between 1816 and 1908. The men were European, and the women were mixed race. Now all of the population has mixed ancestry. In addition, a male contributor of eastern European / Russian descent arrived in the early 1900s. In 1963, when families returned after the evacuation due to the 1961 volcanic eruption, the 200 settlers included four Tristan da Cunha women who brought with them new English husbands. The female descendants have been traced by genetic study to five female founders, believed to be mixed-race (African, Asian and European descent) and from Saint Helena. The historical data recounted that there were two pairs of sisters, but the mtDNA evidence showed only one pair of sisters. The early male founders originated from Scotland, England, the Netherlands, the United States, and Italy, who belonged to three Y-haplogroups: I (M170), R-SRY10831.2, and R (M207) (xSRY10831.2). The male founders shared nine surnames: Collins, Glass, Green, Hagan, Lavarello, Repetto, Rogers, Squibb, and Swain. In addition, a new haplotype was found that is associated with men of eastern Europe and Russia. It entered the population in the early 1900s, at a time when the island was visited by Russian sailing ships. There is "evidence for the contribution of a hidden ancestor who left his genes, but not his name, on the island."
