Priests in a Parish: We use the following convention to show a priest's place among the clergy of a parish: 1/2 means that he is the first priest listed in the Official Catholic Directory (usually the pastor) and that there is a total of two priests at the parish. The shorthand 3/4 means that the priest is listed third on a four-priest roster. See our sample page from the Directory.

Note: The Official Catholic Directory aims to report the whereabouts of Catholic priests in the United States on January 1 of the Directory's publication year. Our working assumption is that a priest listed in the Directory for a given year was at the same assignment for part of the previous year as well. However, Kenedy & Sons will sometimes accept updates well into the year of publication. Diocesan clergy records are rarely available to correct this information. The Directory is also sometimes misleading or wrong. We have tried to create an accurate assignment record, given the source materials and their limitations. Assignment records are a work in progress and we are always improving the records that we post. Please email us with new information and corrections.
