Allen

Hi! This is a run off of my Brannen search. 

Mary Brannen b. 1797 --  the descendant of Thomas Alexander Brannon b. 1723 Ireland, was married to John Allen b. 1785 in SC d. 1847 MS (I have seen his name spelled Allin, also) I don't have his parents names, or grandparents....he is my Allen Dead End!

I am trying to connect with Allens in Ireland, since her family was from Ireland, I wonder if his was also? 

Thanks so much!
