Hat on Family Tree Circles

I have research on Patrick Dickey coming from Ireland. I can't find any information on him in Ireland or his ancestors. He also had some brothers whom he was separated from. Any info on this will be helpful too.
Any descendants of Patrick Dickey I am interested in contacting you. Let me know.

I am a descendant of Patrick Dickey and I can't find any research past his coming to America in 1747.
