Both the Famine Memorial entry and Tippoo Saib passenger list give native place for Mary Fitzgerald as 'Ballygarry, Limerick', a spelling variant of Ballingarry. As with Tipperary there are several locations in Co. Limerick named Ballingarry - a civil parish named Ballingarry (Connello Upper) which is located near the town of Croom, a civil parish called Ballingarry (Coshlea) which is near the town of Kilmallock - both of these parishes have townlands also named Ballingarry but just one also has a town named Ballingarry .. Ballingarry (Connello Upper). When people give the place they live they often give the name of the nearest town, so I think Ballingarry (Connello Upper) is more likely. The nearest large towns would be Rathkeale to the North West and Croom to the East, Adare is a little further to the Norh.
Incidentally the name in brackets after the civil parish name is the barony, which is used to differentiate between parishes of the same name within the one county...
In some cases people used the name of the Catholic parish as their native place - the Catholic Parish for Ballingarry (Connello Upper) is also called Ballingarry, and the parish church was in the town - so Ballingarry parish church, Ballingarry town, Ballingarry (Connello Upper), County Limerick - it can get a little complicated with these overlapping placenames!
I've attached a map of the Catholic Chapels for Ballingarry RC Parish, Co. Limerick - not far to the North is the town of Askeaton the centre of the parish where that Fitzgerald/Hogan baptism was based, and to the north east Croom, where the workhouse for the areas was based.
The other Ballingarry civil parish in Co. Limerick - Ballingarry (Coshlea), was part of a parish Union called Knocklong or 'Knocklong and Glenbrohane'
I had a look for a townland named 'Kiluran Townland, Ballingarry, Limerick' - no matches in either of the Ballingarry parishes in County Limerick - I'll check to see if possibly it's a local name for a crossroads or village. Do you know what the source for this was ?
There are several similar placenames in the mid-west, but none that I've been able to locate in County Limerick e.g. 'Killurane ' in County Tipperary, 'Killuran' in County Clare.
I dont see Convent road, Ballingarry - but there was a Convent just to the west of the town Sr. Mary's, 'Sisters of Mercy', so possibly a local name. The convent only appears on the later maps late 1800s - it's not shown on the earlier c1840s map, on these there's a house called Echo Lodge at the location
I checked into the workhouses and Poor Law Unions in the area and Croom appears to have been ones established later, with Croom officially setup at the end of March 1850 - so not long before the ship departed in early April. 1850. The nearby Unions of Newcastle and Rathkeale previously covered the area - this might account for the Croom Guardian Minute books only starting in 1852. The Limerick Archives website has copies of the Newcastle West Union Board of Guardian Minute Books from 1848, I'll have a look though these for any mention of The Earl Grey Scheme..
I dont think there was a workhouse in Ballingarry, either Newcastle or Rathkeale would have covered the area in the early years, i.e. from 1838, and later the one in Croom would have covered the area - there might have been some sort of temporary accommodation or infirmary for the Poor Law Union at the peak of the famine, which normally would have been close to the workhouse, so either in Croom, Newcastle or Rathkeale.
I'll have further look though the outstanding items, and report back...
