If you are trying to locate the farm, then it’s possible to do that using the Valuation Revision records in the Valuation Office in Dublin. (Not on-line yet so you need to go to the Valuation Office or contact them to see if they’ll help. There may be a fee). Those records will show the plot number in the townland, and you can then compare that with the plot numbers on the maps on the Griffiths Valuation site. (Your family weren’t listed there in 1857, so appear to have acquired the farm sometime later). You can switch between the 1870s map and a modern one, and it has a satellite view as well.
The 1911 census also gives you some information about the farm. Walls were brick or stone, roof was slate or tiles, there were 3 rooms and 4 windows at the front. There were 7 outbuildings: a stable, cowhouse, calf house, dairy, piggery, barn & a shed.
