McGough-Willoughby

My Grandfather Denis McGough married Elizabeth Willoughby, in 1902.Elizabeth died in 1916.Her Mother, Mary Jane Riddell Willoughby died January 20, 1925 in Anamacneil.I am trying to find the Cemetery for that Area.
My Grandfather, Denis, son of Thomas McGough and Elizabeth Daly was one of twins born in Middlesborough, England, Dec 27, 1870, while his parents were travelling abroad.I cannot find a birth certificate for the twins in Middlesborough or in Moneyglen. Elizabeth Daly McGough died August 21, 1910 in Moneyglen and Thomas died January 25, 1935 in Shancobane.I passed a cemetery in 1968 near Carrickmacross and was told all the McGough's were buried there.Could someone give me an idea of what cemetery this could be.
Thank You for your time,
Elizabeth Stanley
