Thanks Trish,
I did come across that site last night and initially found the microfiche version of the church baptism and marriage records, 10 minutes later i gave up trying to read the hand writing and Latin, however a while later I found the transcribed version and physically wrote down all references to the name Iver's on a mud map for future searching.
Also found these statements which I am Googling to find more.
"Ivers was born in Tinryland, County Carlow, the only son of Jemmy Ivers".
"Letters from Jimmy Ivers, Carlow to his son Peter in Dublin in 1798 may be read in Dublin Castle".
"There is also a letter to Matthew Kelly. Miss Annie Cummins, Castletown stated 5 June, 1949 that her father's mother's name was Ivers, a native of Tinryland. The family lived in the road as you go from Carlow to Tinryland. There were three families of them, John, Charlie and Joe. They lived and owned the land from Moore's, Tinryland to Darcy's. The Ivers were masons and great tradesmen. Including Joe, an uncle of Miss Cummins' father, they built the spire of St. Mary's Church. Many of them went to U.S.A.; one of them had a son a priest, Rev. Dr. Ivers; who was home in Fr. John Cullen's time; Dick McDarby had all the papers belonging to him. He was a second cousin of Miss Cummins. Dick's mother was Mary Ivers".
Regards, Mark.
