Hello Mason harris
My grand uncle was a stone mason and built the house, A local man,a relative ,told me the full story but had it wrong about O Gorman evicting the Hayes's as it transpired they were only youths and the house was owned by the local council and not my granduncle ,he was being housed by the council and they paid him to build it so he made it a bit bigger than the standard one .I have a photo of the house.
The council build over 40,000 such houses from about 1880-1916 to house the destitute folloing the great famine.
Everybody in ireland paid a property tax and all property was valued to decide the tax payable.The records were updated on change of ownership so these can be seen at The Valuation Office in Dublin but are not available on line.
Interestingly you mention Heffernan,I met a Heffernan initially ,when I visited Dromkeen area to research my family and he took me to meet this semi reclusive elderly man who happened to be a relation and knew a great lot about my ancestors .I had tea in this Heffernan's house and he died about 2 -3 years ago and is buried in Dromkeen cemetery.He lived in an old house that was half thatched and the other part slated and I now wonder if he was related to you
The 1901 and 1911 census records for Ireland are available on line ,free to search and another useful site is irishorigins.ie where births,marriages and deaths from 1864 to about 1900 are free to search.Deaths may be available later than 1900.
You can also search all parish baptisms and marriages by logging into nli which is the National Library of Ireland and parish records section.Records are difficult to search but if you have a good idea fo place and year you could find useful information.
Feel free to contact me again
