This parish portal identifies Catholic parishes and missions of Washington and Ozaukee Counties, Wisconsin, USA. Included, in parish name order, is a historical overview of the parish and mission followed by the ministering priests and their time of tenure. The information was gleaned from the book THE CATHOLIC CHURCH IN WISCONSIN, from church and historical publications, and from Church of the Latter Day Saints microfilmed parish sacramental registrations up to the year 1920.
With the number of parish merges and closures, it is difficult to determine where parish sacramental registrations can be found. In the Wisconsin Pastoral Handbook 2005 Edition, the availability of these records was detailed. This information can be found here.
Research Tips:
In the early years of the diocese, 1843-1880, when a priest was responsible for a parish and one or more missions, it is not unheard of to find a registration not in the books of the mission church but recorded in the priest's home parish.
In the years 1844-1846, check the Cathedral of St. Peter the Apostle in Milwaukee.
In 1846-1847, check St. Boniface (now Ozaukee and Washington Counties)
Father Caspar Rehrl registrations can possibly be found in any of his missions as he was not very religious in recording these registrations. There is also a LDS film under the name Casper Rehrl and not assigned to any parish or mission.
