Thank you for the information. I was very excited to see the photos, not only of the gravestones, by of the cemetery and church.
I am not surprised to find that Floods are in a family tomb in the body of the Church. It confirms what is written in “The History and antiquities of the Dipcese of Ossory” (1905) This book has been digitalized by Google. According to this book, The Sharpes of Round-wood and the Floods of Middlemount converted the church into a mortuary chapel in the 18th Century. At the time that the book was written there was a slab over a doorway with a coat of arms and the words: “Anthony Sharpe, Esq., A.D. 1776”
There is a marriage connection between the Floods of Middlemount and the Sharps of Roundwood.
From the Ossory Marriage Bond index

Flood, Luke, Middlemount, Esq. married Sharpe, Frances, Queens Co., Protestant, 12 May 1755

This is confirmed by “The History and Genealogy of Fenwick’s Colony, NJ” (1876) by Thomas Shourd, this book has been digitalized and is available on the internet.

“Anthony Sharp, the eldest son of Isaac Sharp, married and had 2 children, on of who whose name was Issaac, died in his minority. The daughter, Francis Sharp, married Luke Flood, of Queens County, Ireland. The Family of the Floods are an ancient family of both England and Ireland. Francis and her husband resided on the great landed estate called Roundwood, that was owned by the first Anthony Sharp.”

Anthony Sharp’s will is recorded in the “Registry of Deeds, Dublin”
In his will he mentions his daughter, Frances. He leaves his rents of estates to his grandson, Robt. Anthony Flood provided he takes the surname of Sharp.

There is evidence that Luke Flood had a son, Edward, by a second marriage.
