A good friend, Charles Bransom, is the principal quasi-official recorder of episcopal lineages. He has been involved in this task for 4 decades, continuing efforts begun in the '30s by Father Albert Perbal, OMI, and Abbot Gabriel Tissot, OSB, and continued in the '50s and '60s by Fathers Andre Chapeau, OSB, Isidore Perraud, CSSp, and Fernand Combaluzier, CM, Msgr. Lamberto de Echeverria, and Mons.Jean Montier.
Charles’ work documenting American episcopal lineages from 1790-1989 was published by the US Conference of Catholic Bishops in 1990 (a follow-up, to bring it up-to-date, is in process). Annually, he issues
Revue des Ordinations Episcopales, a monograph that, for the past 15 years, has documented the details of every Catholic episcopal ordination throughout the world, including date, place, names of consecrator and principal co-consecrators, biographical data related to each new hierarch, and an abbreviated episcopal lineage for each. Those in the Boston area may have seen the lineage of Archbishop Sean O’Malley, OFM, prepared by Charles, that was printed in the
Pilot, newspaper of the Archdiocese of Boston, at the time of Archbishop O’Malley’s assignment. See Charles’ documentation of the late Pope John Paul’s episcopal lineage at:

David Cheney (who posts here as davidc2), an American Catholic layman, maintains an on-line database that documents current and historical information about hierarchs and canonical jurisdictions. His is one of the most thoroughly documented sites on the web and one of a half-dozen that, together, constitute an enormously valuable compendium of data on Catholic hierarchs and jurisdictions. It’s an ongoing work, with historical material continually updated to incorporate newly available data, and information added whenever new hierarchs are named or changes made in any jurisdiction. David offers a free e-mail notification service to keep subscribers immediately abreast of changes. The site is at:
Catholic Hierarchy
von Martin Wolters, a German Catholic layman, documents ecclesiastical jurisdictions and their ordinaries worldwide, as well as the Vatican diplomatic corps, the Vatican dicasteries, and other Curial entities. Both jurisdictional and personnel changes are recorded for all events occurring in or after 1917. The site is available in German and English at:
Die Apostolische Nachfolge (The Apostolic Sucession)
Professor Salvador Miranda, a Cuban-American Catholic layman, has devoted 50 years to collecting data on the cardinalate, The result is a comprehensive, and ever-growing, on-line database that offers extraordinary detail about those on whom the red hat has been conferred:
Cardinals of the Holy Roman Church
Three Norwegian Catholics, Father Claes Tande, Mr. Chris Nyborg, Notary of the Oslo Diocesan Tribunal, and Father Claes’ brother (whose name escapes me at the moment) maintain a web-database that seeks to document the chronological history of all Catholic canonical jurisdictions. Their site, offered in 6 languages, including English, is under continuous expansion. It is at:
Chronology of Erections of Catholic Dioceses Worldwide
Bob Hilkens, a Belgian Catholic layman, created and maintains a large on-line database in English on the history and administrative structures of the nations of the world. Originally limited to secular states, he expanded it some years ago to include the canonical structure of the Catholic Church. His site is at:
States and Regents of the World
Bruce Gordon has expanded a site that initially focused solely on royal houses to include a significant amount of data on ecclesiastical lineages, particularly as they relate to the patriarchates. His site is at:
Regnal Chronologies
Additionally, there is a site maintained by Terry Boyle, an American Catholic layman, which explains the apostolic succession and episcopal lineage of bishops who claim validity through consecration by renegade Catholic and Orthodox hierarchs. Albeit seen through a distorted lensfinder, it offers another aspect of the entire picture. It’s at:
