Fr. Patrick O’Kelly’s Parish Registers: Michigan’s Earliest Catholic Records

Who Father Patrick O’Kelly was

Patrick O’Kelly was a Catholic priest, a native of Kilkenny, Ireland, sent to Michigan around 1829 by Father Gabriel Richard — the well-known Detroit priest and one-time territorial delegate to Congress — specifically to minister to the growing number of Irish Catholic immigrants settling in what was then Northfield, in Washtenaw County. What he built there became one of the genuinely foundational moments in Michigan Catholic history: in 1831, parishioners built him a log church, consecrated as St. Brigid, and the community became the first English-speaking Catholic parish in the state — three years before Detroit’s own Most Holy Trinity, which served the city’s French-speaking Catholics. Local Irish settlement in the area was substantial enough that Northfield became known as “New Ireland,” and by 1878 more than half the farms in the township belonged to Irish families.

O’Kelly’s work wasn’t confined to one township. He ministered across a wide circuit for decades, celebrating what’s recorded as Ann Arbor’s first Catholic Mass in a private home on July 12, 1835, and continuing to serve congregations well beyond Northfield into the 1840s and 1850s. The parish he founded went through a rename — “St. Brigid” became “St. Patrick’s” — and the site eventually earned both a Michigan State Historic Site designation and a place on the National Register of Historic Places.

Baptisms and marriages, congregation by congregation

The registers that carry O’Kelly’s name today are baptismal and matrimonial records for the Catholic congregation spread across Ingham, Livingston, and Oakland counties, covering the years 1843 through 1859. That date range runs later than his earliest work in Northfield, which tells you something important: O’Kelly was still actively serving a wide circuit of Catholic families well into the 1850s, decades after his initial 1829 arrival, and the surviving register reflects that later, broader stretch of his ministry rather than his very first years in the territory.

The register covers several distinct congregations O’Kelly served across that circuit:

Entries in the register typically give the names involved in a baptism or marriage and a date; some entries also note the specific town or parish, though this detail isn’t consistent across every record. That inconsistency is worth expecting going in — a circuit-riding priest serving seven or more congregations across three counties, working by hand in the 1840s and 1850s, wasn’t keeping a standardized modern database. I’ve come away from records like this one thinking they’re still remarkably rich for the period, but they reward patience rather than a quick name search.

Why a record like this matters more than it might look

Michigan didn’t require statewide birth, marriage, or death registration until Public Act 194 of 1867 took effect, and even then, compliance in rural areas took years to become reliable. For any Catholic family living in one of the counties O’Kelly’s circuit covered before 1867, a parish register like this one is frequently the only surviving documentation of a baptism or marriage from that entire period — there’s no birth certificate to fall back on, because the state wasn’t issuing one yet. It also matters as a piece of Michigan Catholic history in its own right: O’Kelly’s parish predates many later dioceses and reflects a period when a single circuit-riding priest was the entire institutional Catholic presence for dozens of scattered farm families.

Where the O’Kelly register is held today

A microfilm copy of the O’Kelly baptismal and matrimonial register is available for personal research at the Library of Michigan in Lansing. I’d plan a full visit around it rather than a quick stop, since it is not available for interlibrary loan — researchers need to either come in person or work with the library directly to access it.

How to search the O’Kelly parish registers

1. Confirm the family was Catholic and living in Livingston, Oakland, or Ingham County between 1843 and 1859 before assuming this register applies — O’Kelly’s circuit was wide, but not statewide.
2. Identify which of the seven congregations is most likely, based on where the family is known to have settled (see the table above for church-to-county mapping).
3. Plan a visit to the Library of Michigan in Lansing to view the microfilm, since it isn’t available through interlibrary loan.
4. Cross-reference any entry against county land and probate records from the same period, which can confirm a family’s presence in a township even when a register entry is sparse.
5. If the family isn’t in the register, check whether a later parish took over record-keeping — as Michigan’s Catholic population grew, dedicated resident priests gradually replaced circuit-riding ministries like O’Kelly’s.

Frequently asked questions

Who was Father Patrick O’Kelly? A Catholic priest from Kilkenny, Ireland, sent to Michigan around 1829 by Father Gabriel Richard to minister to Irish Catholic immigrants in Washtenaw County. He founded St. Brigid Parish — later St. Patrick’s — in Northfield Township in 1831, the first English-speaking Catholic parish in Michigan.

What does the O’Kelly parish register actually contain? Baptismal and matrimonial entries for the Catholic congregation across Ingham, Livingston, and Oakland counties, covering 1843 through 1859, typically giving names, a date, and sometimes the specific town or parish.

Where is the O’Kelly parish register held today? A microfilm copy is available for personal research at the Library of Michigan in Lansing, and it is not available for interlibrary loan.

Which churches are covered in the O’Kelly register? St. Patrick’s Pinckney, St. Joseph’s Green Oak, St. James’ Hartland, and St. Andrew’s Deerfield Center in Livingston County; St. Patrick’s White Lake and St. Thomas Pontiac in Oakland County; and St. Patrick’s Bunker Hill in Ingham County.

Why are early Catholic parish registers important for Michigan genealogy? Because Michigan had no statewide vital records requirement until 1867, and Catholic parishes had been keeping their own baptismal and marriage registers for decades before that — often the only surviving record of a birth or marriage from that period.
