thanks to all who replied to my query. I have now discovered that Owen Brennan was born in Drumgarra Co Monaghan and had at least three sisters and a number of cousins who lived in the Newtownsaville/Eskra area of co. Tyrone. He was connected to McSorley, Hackett, McGinn and Carney families. Owen died in 1918 apparently he bequeathed most of his business to his two nephews Hackett and McSorley but not 100% sure of this. Assembling the history of the Duffy family of Tullynahinera Co monaghan and would be very grateful for any additional details. Roisin
