I haven't checked the site in years...but when I do I get pulled in! A Lally cousin of my grandmother's had said some of our family came from Ballina. She however was the daughter of a Kane and Lally who who were descendents of Mary McNamara married to Patrick Kane. So much be different family.
There was a large Manley family I am related to from Archbald. They lived next to Anthony and Sarah (White) Carey.
Does any of the above info fit into your Manleys?
