Hello Paul
The Hugh Scollen I know of was born on Galloon Island on Lough Erne, near Newtonbutler, Fermanagh in 1854. His father was Patrick Scollen and his mother Margaret Scollen (nee Macdermott) Margaret died in 1847 leaving three young children, Constantine, Rose and Hugh. Patrick moved to Bradford to work leaving the three children with his brother Owen and his wife in Galloon. Patrick married Catherine MacEvoy and in 1851 the family moved to Bradford. Two more children were born there. They then moved to Crook, Co Durham and had five more children. Hugh was the great grandfather of my friend Hugh Scollen.
I am presently completing a biography of Constantine who became a missionary priest among the native peoples of Canada and the US and have set up a Wikipedia page for him.
Hope this helps you
