Cunniamstown comes in two flavours Big and Little so you will need to determine which you need. I have created both categories for you.
That parish by the way is a v4.0 parish free space page and all Irish civil parishes which carry a version number above 3.2 have the full text of all as yet uncreated townland categories, just in case no one is around to make the category. IF you are computer literate and au fait with cut and paste beyond just simple words then you will find the instructions to create townland categories linked on the parish page under the heading Townland Category Information Boxes.
If you do not feel comfortable doing all that, as many do not, then please by all means continue reaching out for assistance.
