Hi.
I believe I am also a descendant of this Thomas "the Immigrant" Hagan. My Hagans come from New Haven and Louisville in Nelson County, KY, and from what my grandmother tells me they originated in Maryland and can be traced back to a Thomas Hagan. I would love to see this website you were talking about. There are huge gaps in my records and it would be great to verify that I'm doing the lineage properly, especially with the frequent repitition of first names.
