Seeking help tracing Mills family – St Peter’s Parish, Dublin (mid-1800s)

Hello — I’m researching my Irish ancestry and hoping for guidance with Church of Ireland records in Dublin.

I’m tracing my great-great-grandmother, Kate (Catherine) Mills, daughter of George Mills, baptized at St. Peter’s Church of Ireland parish, Dublin, circa 1852–1854. She later emigrated to New York in the 1870s.

I currently have St. Peter’s parish baptism records, a Dublin marriage record, and a passenger list, and I’m trying to better understand parish boundaries, residences, and any additional Mills family records connected to St. Peter’s / north inner-city Dublin.

If anyone has experience with St. Peter’s CoI registers, Dublin CoI archives, or Mills family research, I’d greatly appreciate any guidance. Happy to share details privately.

Thank you.

My long-term aim is to clearly document this family line for formal purposes in the future, so I’m trying to be as accurate as possible with parish, civil, and migration records. Any local knowledge, confirmation, or guidance on St Peter’s Parish (COI), Mountjoy Square, Henrietta Street, or Dublin records from the 1850s–1870s would be sincerely appreciated.

St. Peter's Church of Ireland is a large parish located South of the Liffey and covers parts of south city and also parts of county Dublin (at the time).

The parish Church was on Aungier street.

The other streets are the opposite side of the city, i.e. Northside, with Henrietta Street split between St. Michan and St. Mary's parish and Mountjoy Square in the parish of St. George

I've marked approx. location of each on the map image below :

St. Peter's CofI - Red

Henrietta Street - Blue

Mountjoy Square - Green

The distance from Mountjoy Square to Aungier Street and St. Peter's is about 2km (~1.25 miles) as the crow flies.

In Thom's 1852 directory the occupants of 1 Mountjoy Square East are John Fenton Esq., principle householder, along with a Trevor Alexander Fenton - possibly the family that your George Mill was employed by. The same directory shows that the householder at 6 Hennrietta Street was a Charles Geoghegan a solicitor - the street is adjacent to King's Inn and later many of the formerly grand houses became tenements..

Message from Andrew Fest:

Hello,

Thank you for the responses so far on the message board.

I am currently gathering and organizing the supporting records (baptisms, marriage records, and emigration data) and will upload them as soon as possible. I wanted to share this update by email as I’ve been unable to post the reply from my mobile device.

I appreciate any guidance in the meantime.

Kind regards,

See below for a map of St. Peter's Civil parish boundary overlayed on a modern map from the townlands.ie website, this uses Openstreetmaps (OSM) as it's basis. You can also view the other parishes on the same website - see this link : https://www.townlands.ie/dublin/ (right click and open link in new tab/window or copy link) scroll down for the civil parishes, in many cases these are the same as the Church of Ireland Parishes.

St. Peter's Civil Parish - OSM/Townlands.ie

It looks like your Mills/Smyth family moved around quite a bit, possibly related to the occupation of George - married at St. Peter's South city/county giving residences at Pembroke Place and Herbert Street which are to the east of the city - but just inside St. Peter's CofI parish. Giving residences at Henrietta Street and Mountjoy square "North side" at the time of children's baptisms…

Thom's 1880 map - St. Peter's CofI Church (red), Herbert Street (blue)

I looked into the residences for George and Catherine at the time of their marriage - 3 Herbert St. for George is off Baggot Street Lower in the east of the south city, in 1840 (Pettigrew & Oulton) the principle occupant is listed as a Joseph Kincaid esq., he is listed as a land agent in later directories. The houses on this street consist of a terrace of large red-brick houses with 4 stories over a basement/kitchen level - probably large enough for servant quarters on the top floor. Catherine's address at 15 Pembroke place is nearby and the householder is listed as Lord Viscount Netterville.

Working back on the Mills side without some further clues could be difficult as George snr. will probably not be included in directories or land records as he likely lived in accommodation provided by his employer. The Smyth side is probably a better option for further searches a) the bride's father is a farmer so likely to have held or leased some land, and b) he has an uncommon name , Nataniel - although it's uncertain at this point that he was alive at the time of marriage. Nathaniel is not likely to have been a farmer in the area of the marriage as it was built up even back then. A check of Griffith's primary Valuation records shows under 20 possible matches for him, but none in or even near Dublin city - most in Co. Cork, some in Co. Antrim followed by Co. Cavan Co. Waterford and Co. Kerry , these date from 1853/56/60.

Two possible further clues on the marriage records are the witnesses - Herbert Smyth and Elizabeth Smyth, likely relations of the bride … possibly siblings ..

Thank you — just to clarify, my confirmed ancestor is Kate (M.) Mills, born c.1855, who later immigrated to New York in 1875 and married John Walton.

I’ve located a Church of Ireland marriage for George Mills & Mary McKenzie (1855, Donnybrook) and am trying to determine whether this George Mills could be connected to Kate Mills. Any guidance on how to assess that connection would be greatly appreciated.

Hi Roger,

As mentioned, I’m attaching a small set of key records I’ve gathered so far (baptism records from St. Peter’s Parish, Dublin, and the 1875 passenger list).

I appreciate any guidance on next steps or additional records that may help.

Best regards,

Andrew
