Ancestors from Ireland

My own research is heading overseas on my father's side, to county Wexford in Ireland. I know very little about that branch of my family, so I'm in for a challange.

My maiden name is Furlong, which I have learned comes from Ireland. I know nothing about my father's side of the family beyond the name of my Grandfather. I suspect he's from Ireland but can't really be sure.

If you have family from Ireland, there are several good resources to help with Irish genealogy.
