Cellach I is traditionally said to have been the first Bishop of the Scots (fl.
 878x889-906x), the bishopric later based at St. Andrews.
 He is mentioned in the historical writings of Walter Bower and Andrew of Wyntoun as a bishop of St. Andrews, but no pre-15th century sources say anything more than merely "Bishop".
 Wyntoun and Bower make him bishop as early as the reign of King Giric of Scotland (877x878-885x889).
 He was still bishop in the reign of King Causantín II of Scotland in 906 when, "in his sixth year king Causantín and bishop Cellach upon the hill of credulity near the royal city of Scone, pledged themselves that the laws and disciplines of the faith, and the rights in churches and gospels, should be kept in conformity with the [customs of the] Gaels".
 One interpretation of this passage is the demise of the "Pictish church" to the reforming Gaels, however it is certain that by the 15th century the bishop-list of the principal Scottish see was looking back at Cellach as its first bishop.
 His death date is unknown, but unsurprisingly he was certainly dead by the 960s when his successor Fothad I died as bishop.
José Francisco Ulloa Rojas was born in Cartago, Costa Rica, on October 1, 1940.

Paulinus (died 10 October 644) was a Roman missionary and the first Bishop of York.
 A member of the Gregorian mission sent in 601 by Pope Gregory I to Christianize the Anglo-Saxons from their native Anglo-Saxon paganism, Paulinus arrived in England by 604 with the second missionary group.
 Little is known of Paulinus' activities in the following two decades.
James the Deacon (died after 671) was a Roman deacon who accompanied Paulinus of York on his mission to Northumbria.
 He was a member of the Gregorian mission which went to England to Christianize the Anglo-Saxons from their native Anglo-Saxon paganism, although when he arrived in England is unknown.
 After Paulinus left Northumbria, James stayed near Lincoln and continued his missionary efforts, dying sometime after 671 according to the medieval chronicler Bede.
Alexis Canoz S.J., (8 September 1805 – 2 December 1888) was a Jesuit missionary in India and was the first bishop of Trichy.

John O'Reily (born John O'Reilly, 19 November 1846 – 6 July 1915) was an Australian Roman Catholic clergyman, the first Bishop of Port Augusta, and the second Archbishop of Adelaide.
 Born in Kilkenny, Ireland, O'Reily studied for the priesthood in Dublin.
 Upon his ordination in 1869, he migrated to Western Australia, serving as a parish priest in Fremantle, and founding a Catholic newspaper there.
 When the Diocese of Port Augusta was established in 1887, Pope Leo XIII named O'Reily as its first bishop.
 Concerned about the financial position of the diocese (which had inherited significant debt from the Diocese of Adelaide), he accepted the posting reluctantly.
 As bishop, he greatly improved the financial position of the new diocese, reducing its debt by half and earning a reputation as a competent administrator.
Augustin Pacha (November 26, 1870—November 4, 1954) was a Romanian cleric, the first bishop of the Roman Catholic Diocese of Timișoara.
 Born into a Banat Swabian family in Măureni ("Moritzfeld"), Caraş-Severin County, he was the twelfth of thirteen children and his father was a shoemaker.
 Following theological studies at the diocesan seminary in Timișoara, he was ordained a priest in 1893 in the city's Roman Catholic cathedral.

 Three years later, he became the first Bishop of Timișoara, a diocese succeeding the former one at Cenad, the last bishop having departed Romania in 1923, leaving Pacha as Apostolic Administrator.
 In February 1934, alarmed by rising Nazi sentiment among the Swabians of his diocese, he visited Adolf Hitler, receiving a polite reply to his complaints but no concrete action.

Cormac, Bishop of Dunkeld (fl.
 x1114-1131x) is the earliest recorded Bishop of Dunkeld in the 12th century, although he was not the first bishop of Dunkeld.
 It is possible, that he was the first bishop of Dunkeld distinct from the abbot, but there is no evidence for this.
 He appears in two rather doubtful charters of King Alexander I of Scotland, in several charters of King David I of Scotland and in the Gaelic "notitiae "on the "Book of Deer", rendering a floruit of on or before the year 1114, to on or after the year 1131.
 The last source calls him "Cormac escob Dúno Callenn", Cormac bishop of Dunkeld".
