Hello Peggy, we do not appear to have an active volunteer locally as you query has not been picked up as yet and I am not in a postion to go there. However if you go to this site https://www.townlands.ie/limerick/owneybeg/abington/clonkeen/farnane/ you will see the general area. You can also visit this site http://www.askaboutireland.ie/griffith-valuation/index.xml?action=nameSearch this will show you what families lived in the area in 1851, there are a total of 15 Tucker families in Limerick and your area appears to be Abington, there are no Houragan in Abington (there are some elsewhere) but there are the more common spelling of Hourigan. If you click on the icon on the selected family you will see a plot number, another icon gives you a map and you can search for the preferred plot number, this is not easy but doable, once you have identified it, there is a tab bar on the top right and you can move it to the left to get the modern map, as mentioned it is tricky to do but you can get to Google streetview and have a look yourself. I understand the maps though are done later circa 1880 but if you wish to use a subscription site you may get the originals, (Find My Past). All maps are here if you wish https://www.osi.ie/
While there has been a lot of development in Ireland obviously since I think that area would still be fairly rural.
