Thank you Annette. It is very possible that Denis Scanlan was not the eldest son, therefore, he may have married into the Hegarty family and worked the Hegarty farm. The sponsors for my great-grandfather, John Scanlon, were Patrick and Ellen Hegarty. It is possible that these (2) people were Margaret's parents. As I looked at the sponsors for the rest of the children, the surname Scanlan was not mentioned once. I wonder if Denis was not close to his family or maybe he was an orphan. I was told that it was very unlikely that he would have originated in Kerry. Even though his first son was named John, that doesn't mean that it was Denis' fathers name. The second son was Patrick, possibly named after Margaret's dad. So, I'm stuck, not sure where to look next.
