So after long years of searching i have finally crossed the ocean and found the embark point of my G G G G Grandfather. Seems he came to New York via Queenstown Ireland County Cork(now known as Cobh Ireland). So it seems I am of Irish desent!! well i know the rules. Check Check and RE check the source and find verify it. Thats why I am posting here. Does anyone have a leads on a GOOD source for Irish history research. Like i said i know he left Cobh Ireland, but not much else.. where does one go from here.

Thank for any help
