Jean Pierre (priest)
breton missionary and martyr (1831–1873)
Jean Pierre (29 September 1831 – 16 September 1873) was one of five Breton missionary priests to Louisiana who made a sacrifice of their lives in the 1873 Yellow Fever Epidemic in Shreveport, Louisiana. The group is collectively known as the Shreveport Martyrs. On December 8, 2020, Bishop Francis Malone of the Diocese of Shreveport declared him to be a Servant of God, opening the diocesan phase of inquiry into a Cause of Beatification and Canonization. In 2022, the Vatican's Dicastery for the Causes of Saints permitted Father Pierre and the other four Shreveport Martyrs to proceed for consideration as a single Cause. Peter B. Mangum serves as the Episcopal Delegate for the Cause.
Born in Lanloup, France to Guillame and Claudine Pierre, he entered the Petit Seminaire de Tréguier on 3 August 1845, weeks before his fourteenth birthday. He joined a student association known as The Congregation of the Most Holy Virgin, a community dedicated to the cultivation of deeper personal piety. This association required a formal written pledge which Pierre signed, which reads, “after satisfying a time of approval, Jean Pierre of Lanloup is received into the Congregation of the Most Holy Virgin established in the ecclesiastical school.”
On 1 October 1852, Pierre entered the Grand Seminaire de Saint-Brieuc. A signed document from the bishop of Saint-Brieuc, Jacques-Jean-Pierre Le Mée, acknowledged Pierre’s placement as second in his graduating class. Bishop Augustus Marie Martin recruited him to come to the newly erected Diocese of Natchitoches in Louisiana and Pierre departed the port of Le Havre on 8 October 1854.

Why this record matters
The phrase “breton missionary and martyr (1831–1873)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 5, 2025. The linked authority identifier is Q130421186. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1831, 1873, 2020 and 2022.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
