Hello, I have an ancestor from Ireland and I am having a hard time also trying to locate the family. I am by no means a genealogy expert but I looked up and found that the name Casey is principally located in counties: Cork, Kerry, Dublin, and Limerick. This family tree endeavor is unfortunately a "long hard road". In your note am I to assume that Eugene was James' son? What was Eugene's wife's name? If you need some websites I might be able to give you a few if you are interested. I noticed that you are in Fort Collins, well I am in Colorado Springs. So hello neighbor! Please email me if you would like some more information. Barbara
