Do you know the names of his children and what became of them? My grandfather, Thomas Joseph Frain, MAY have been one of Dominick's sons. He was born, I believe, in 1877, and christened in Tobercurry. He was in the U.S. by 1896 and joined the army in time to fight in the Spanish American War. Fortunately, the war ended before he made it to the Philippines. He served long enough to get a veteran's funeral and is buried at Ft. Sam Houston, Texas.
As unpopular as the Irish were then, he claimed all his life to have been born in America. I spent a lot of time and effort looking for him in Connecticut, only to find it was not the same Thomas Joseph Frain. Crap.
I've heard since that his father was Dominick and his mother was Mary Roper. I heard he had brothers named Martin and Dominick, and likely he also had sisters. They're all dead by now, so I have no way to know for sure. Is there a chance that your Dominick might be my GGrandfather?
