James Ussher
Archbishop of Armagh (1581-1656)
James Ussher (or Usher; 4 January 1581 – 21 March 1656) was the Church of Ireland Archbishop of Armagh and Primate of All Ireland between 1625 and 1656. He was a prolific Irish scholar and church leader, who today is most famous for his identification of the genuine letters of the church father, Ignatius of Antioch, and for his chronology that sought to establish the time and date of the creation as "the entrance of the night preceding the 23rd day of October ... the year before Christ 4004"; that is, around 6 pm on 22 October 4004 BC, per the proleptic Julian calendar.
Education
Ussher was born in Dublin to a well-to-do family. His maternal grandfather, James Stanihurst, had been speaker of the Irish parliament. Ussher's father, Arland Ussher, was a clerk in chancery who married Stanihurst's daughter, Margaret (by his first wife Anne Fitzsimon), who was reportedly a Roman Catholic.
Ussher's younger and only surviving brother, Ambrose, became a distinguished scholar of Arabic and Hebrew. According to his chaplain and biographer, Nicholas Bernard, the elder brother was taught to read by two blind, spinster aunts. A gifted polyglot, he entered Dublin Free School and then the newly founded (1592) Trinity College Dublin on 9 January 1594, at the age of thirteen (not an unusual age at the time). He had received his Bachelor of Arts degree by 1598 and was a fellow and MA by 1600 (though Bernard claims he did not gain his MA till 1601).
This brief starts where responsible research should: with the source description of “James Ussher” as archbishop of Armagh (1581-1656). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as archbishop of Armagh (1581-1656). Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q333481. VIAF identifies the subject as 68969862. The Library of Congress control number is n50077637. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1581, 1656, 1625 and 1592.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
