Arch Bishop Hughes , although born in Tyrone, did live in Dernaved in Errigal Truagh from the time he was a small child to the time he left Ireland for America. Dervaved is a Townland that is adjacent to Mullaghselsana. It is very possible that Bishop Hughes was somehow related to the McGeoughs.
Peter McGeough was the brother of my great-great grandfather, Arthur McGeough. Peter is the direct ancestor of Ann Magno ( Massachussets).
Although I do not have direct proof, I am convinced that your Arthur McGeough was an Uncle of my Arthur McGeough and a brother to Bernard McGeough ( my great-great-great grandfather). I believe my Bernard McGeough to be the Bernard listed at Mullaghselsana in the 1826 Tithe Applotment Book or possibly the Bryan McGeough listed in Aghamackalinn ( adjacent to Mullaghselsana) in the 1826 Tithe Book and 1860 Griffiths Valuation. Bryan is an old Irish form of the name Bernard.
My wife and I briefly visited the Errigal Truagh area this past March. We did some bicycle riding and also were given a tour by Seamus McCluskey a local historian from Emyvale.
We stopped at Old Errigal Graveyard as well as the Parochial House at Ballyoisin. We met Father Nolan and Geraldine Treanor, who works at the Parochial Center. Geraldine , whose mother grew up in the Corley house in Cavan Moutray ( also adjacent to Mullaghselsana) provided me with further records of the McGeoghs in Errigal Truagh.
We also stopped at St. Patricks in Clara. Unfortnately, I did not see any McGeough headstones in the Cemetery at St. Patricks. However, this is not surprising, as our McGeough ancestors are probably buried in the older graveyards in the Parish.
We also met a man nnamed Al McGeough, who owns a taxi/bus service. Al drove my wife and I back to Monaghan Town from Emyvale. He was in shock when I told him my ancestors were McGeoughs. Al lives in the South East part of the Parish of Errigal Truagh ( near Emyvale) and most likely is not related to our McGeoughs from the Northwest part of Errigal Truagh.
