Betsy Baker

Betsy Baker (August 20, 1842 – October 24, 1955) was born Betsy Ann Russell in Great Brington, England, emigrated to the United States, settled in Nebraska, and became the world's oldest person. She lived for 65 years in Johnson County, where she was called "the Queen mother of the Johnson County Fair" in 1953. At age 107, she received a congratulations letter from president Harry S. Truman. She was featured upon her 112th birthday in the US Army magazine Stars and Stripes. She died in Tecumseh, aged 113 years and 65 days.

Baker was the first supercentenarian listed by Guinness World Records as the world's then-oldest person. In 2002, researchers confirmed she had been the world's oldest living person by modern verification standards for an unknown period of time prior to her death in 1955. She was the second person in the world (after Delina Filkins) to have reached the age of 113 and to have been validated by modern standards.

Jeanetta Thomas

Jeanetta Jane Thomas (2 December 1869 – 5 January 1982) of Llantrisant, Wales, was a British supercentenarian and was mentioned in the Guinness Book of Records in the 1980s. She was a child of quarry owning parents. Thomas spent her youth in London working as a seamstress. At the age of around 40, she returned to Wales to open a drapery shop, which she ran until the age of 98. She was also the oldest living person in the United Kingdom from 20 October 1980 until her death, at the age of 112 years and 34 days.

From the age of 107, Thomas resided at a nursing home at Cowbridge, Wales. A photograph of her, which was taken the day before her 112th birthday, appeared in The Times. Had Thomas lived another six days, she would have broken the British longevity record which at that time was held by Alice Stevenson. Thomas still holds the record for the oldest Welsh-born woman ever, although Welshman John Evans and English-born Anna Eliza Williams (who died in Wales) both lived longer.

Daisy Adams

Daisy Irene Adams (née Woodward; 30 June 1880 – 8 December 1993) was for about nine months the oldest person in the UK, between 17 March 1993 and her death on 8 December 1993. She was from Church Gresley, Derbyshire. She died at the age of 113 years and 161 days, and outlived her husband and three of her five children. Her husband died on the first day of the Battle of the Somme, meaning that she was widowed in her thirties. Adams was a teetotaler and ate little. Her son Ted put her longevity down to "living a quiet life".

Rebecca Hewison

Rebecca Hewison (née Ramsdale; 19 October 1881 – 22 September 1994) was a British supercentenarian and the oldest person living in Britain until her death aged 112 years, 338 days. Born in Grimsby, Hewison was the fourth child of six born to Will, a timber merchant, and Betsy-Ann Ramsdale. She married George Hewison, a stonemason, in Grimsby in 1905. In 1938 she moved to be with her daughter Frances in North London. Later in 1963 the family moved to Berrynarbor in Devon until Hewison was 105 when she returned to her hometown of Grimsby. In 1990 she met the Queen Mother at RAF Scampton. She also was a supporter of Grimsby Town football club and met the team in 1991, the year she turned 110 and also the year that the team completed a second successive promotion. Hewison was also taken for flights in aeroplanes and helicopters at Humberside Airport.

Askew was born and died in Loughton, Essex. She was born to Arthur George Askew and Susan Elizabeth Askew née Ellis, prosperous cartage contractors, cab proprietors, and landowners. Lucy had five other siblings, all of whom she outlived, although three of them also lived past 100. Askew never married and was a staunch Christian, attending the Loughton Union Church. Askew moved into a nursing home when she was 106 and survived a leg operation at 108. She was in good health until shortly before her death when she died peacefully in her sleep. She attributed her longevity to a modest lifestyle.

Amy Hulmes

Hulmes was the youngest of nine children, and gave up smoking at the age of 84. She could reportedly still touch her toes at the age of 105.

Edith Ingamells

Edith 'Judy' Ingamells (née Gude;12 January 1894 – 1 March 2006) was the oldest living person in the United Kingdom, following the death of 113-year-old Lucy d'Abreu on 7 December 2005, until her death aged 112 years 48 days. Judy's successor as the UK's oldest living person was Emmeline Brice.

Edith was born in Maidenhead, Berkshire, on 12 January 1894. Her parents were George and Harriet Gude. The 1901 Census of England and Wales recorded Edith living at 9 High Street, Maidenhead, aged seven. Her father, George, then aged 53, was working as a photographer. By the time of the 1911 Census, Edith was living at 'The Cedars', 44 Bridge Street, Maidenhead, aged 17. George, then aged 63, was working as a public caterer, while Edith was an apprentice milliner.

At the beginning of the Second World War, Edith, nicknamed 'Judy', moved to Enfield, Greater London. She married Percy Ingamells, in St. Martin, London in 1914, aged 20. Percy worked as a wholesale florist for a family firm based Covent Garden. Edith and Percy had three children, daughters Monica (b. 1915), Pauline (b. 1921) and Patricia (b. 1925).

Edith lived in other areas around England, and worked as a milliner before coming back to settle in Enfield in 1990.

In 1994, Edith celebrated her 100th birthday, becoming a centenarian and in 2004, celebrated her 110th birthday, becoming a supercentenarian. Edith's daughter, Patricia Bull said, at the time of her mother's 111th birthday, that the secret of her longevity was to "never look back, always look forward, which she is certainly doing". When serenaded with wartime songs on her 112th birthday, Ingamells responded "I don't like war songs. Who wants to remember something as horrible as the war?".

Edith died at Chase Farm Hospital, Enfield on 1 March 2006, aged 112. Her death certificate records her cause of death as I (a) Pneumonia (b) Immobility (c) Osteoporotic Fracture of Pubic Ramus. Her death was registered by her daughter, Patricia. At the time of her death, Edith had three daughters, five grandchildren, four great-grandchildren and two great-great grandchildren.
