Hippolytus or Hipolit (died c. 1027) was an early medieval archbishop of Gniezno.
 His place and date of birth date are unknown but the medieval historian Jan Długosz claims that he was of noble birth and a Roman citizen.
 Modern scholars generally agree that he was not Polish.
Theobald of Bec (c. 1090 – 18 April 1161) was archbishop of Canterbury from 1139 to 1161.
 He was a Norman; his exact birth date is unknown.
 Some time in the late 11th or early 12th century Theobald became a monk at the Abbey of Bec, rising to the position of abbot in 1137.
 King Stephen of England chose him to be Archbishop of Canterbury in 1138.
 Canterbury's claim to primacy over the Welsh ecclesiastics was resolved during Theobald's term of office when Pope Eugene III decided in 1148 in Canterbury's favour.
 Theobald faced challenges to his authority from a subordinate bishop, Henry of Blois, Bishop of Winchester and King Stephen's younger brother, and his relationship with King Stephen was turbulent.
 On one occasion Stephen forbade him from attending a papal council, but Theobald defied the king, which resulted in the confiscation of his property and temporary exile.
 Theobald's relations with his cathedral clergy and the monastic houses in his archdiocese were also difficult.
Raymond III (1140 – September/October 1187) was count of Tripoli from 1152 to 1187.
 He was a minor when Assassins murdered his father, Raymond II of Tripoli.
 Baldwin III of Jerusalem, who was staying in Tripoli, made Raymond's mother, Hodierna of Jerusalem, regent.
 Raymond spent the following years in the royal court at Jerusalem.
 After he reached the age of majority in 1155, he participated in a series of military campaigns against Nur ad-Din, the Zengid ruler of Damascus.
 In 1161, he hired pirates to pillage the Byzantine coastline and islands to take vengeance of the Byzantine Emperor Manuel I Komnenos who had refused to marry his sister, Melisende.
Peter Vasilievich Obolensky (Russian: Пётр Васильевич Оболенский ), nicknamed The Naked (Russian: Нагой ) (birth date unknown – died 1510), was a Russian prince and boyar in the service of the Grand Princes of Moscow Ivan III and Vasili III.
In Costa Rica, in recent years, a cédula de identidad, has been a credit card-sized plastic card.
 On one side, it includes a photo of the person, a personal identification number, and the card's owner personal information (complete name, gender, birth date, and others), and the user's signature.
 On the reverse, it may include additional information such as the date when the ID card was granted, expiration date of the ID card, and other such as their fingerprints, and all the owner's information in matrix code.
 Every Costa Rican citizen must carry an ID card immediately after turning 18.
Leonard Digges (c.1515 – c.1559) was a well-known English mathematician and surveyor, credited with the invention of the theodolite, and a great populariser of science through his writings in English on surveying, cartography, and military engineering.
 His birth date is variously suggested as c.1515 or c.1520 (but certainly by 1530).
James Walter McCord Jr. (born June 26, 1924) is a former CIA officer, later involved, as an electronics expert, in the burglaries which precipitated the Watergate scandal.
Saint David (Welsh: Dewi Sant , Latin: "Davidus" ; 500 c. 589) was a Welsh bishop of Mynyw (now St Davids) during the 6th century; he was later regarded as a saint.
 He is the patron saint of Wales.
 David was a native of Wales, and a relatively large amount of information is known about his life.
 However, his birth date is uncertain: suggestions range from 462 to 512.
 He is traditionally believed to be the son of Saint Non and the grandson of Ceredig ap Cunedda, king of Ceredigion.
 The Welsh annals placed his death 569 years after the birth of Christ, but Phillimore's dating revised this to 601.
Alfred Baldwin (born June 23, 1936) was the so-called "shadow man" in the Watergate break-in and the ensuing Watergate scandal.

 He was born in New Haven, Connecticut.
