Edgar Charles Sumner Gibson (born 1848 in Fawley, Hampshire, England, died 1924) was the 31st Bishop of Gloucester. He was born into a clerical family  and educated at Charterhouse and Trinity College, Oxford. Ordained in 1872, his first post was as Chaplain at Wells Theological College, rising to Vice Principal in 1875. His next post was as principal of Leeds Clergy School and he later became Rural Dean of the area and Vicar of Leeds Parish Church.
In 1905 he was elevated to the episcopate where he remained until his death 19 years later.
Gibson was born at Fawley, near Southampton. He was the son of Rev William Gibson (1804–1862) and his second wife Louisanna Sumner (1817–1899). Louisanna was the eldest daughter of Charles Richard Sumner (1790–1874) (who had been the Bishop of Llandaff, 1826–27, and served as Bishop of Winchester from 1827–1868) and Jennie Fanny Barnabine [Maunoir] (1794–1849). She was therefore the niece of Charles' elder brother John Bird Sumner who served as Archbishop of Canterbury from 1848–62. Arthur's father William, had married Arthur's mother in 1837, the year after the death of his first wife Eliza Maria, (1808–1836). Louisanna was in fact the first cousin of William's first wife with Eliza having been the third daughter of John Bird Sumner.
Edgar was born in Fawley, Hampshire where his parents had moved in 1840 and where William became Rector. Edgar had two older half siblings from his father's first marriage: Marianne (May) (1832–1845) and John Sumner (1833–1892). From his father's second marriage he had six older siblings, Ella Sophia (1838–1928); Emily Louisa (1840–1887); Ada Frances (1841–1893); and Edith Harriet (1842–1922); Arthur Sumner (1844–1927) and Herbert William Sumner (1846–1923). He also had four younger siblings, Walter Sumner (1849–1918); Rosa Fanny (1850–1904); Florence Jennie (1853–1911) and finally Alan George Sumner (1856–1922). His elder brother, Arthur Sumner Gibson was a rugby union international, playing in the first international match in 1871.
