I'm also searching for information on the Devlins from Co. Donegal. My great, great, great grandfather was Cornelius "Connell" Devlin b. abt 1800-1805 in Barnesmoor, Co. Donegal, Ireland. He came to the US bef 1857 and was married to Margaret Smiddy. They lived in Summerhill, Cayuga Co., NY where he was a farmer. He died in 1918 at the age of 114 was an inveterate smoker, had a red handlebar mustache and drank whiskey every day. Any information on the Devlins would be greatly appreciated as we are "stuck".
