Hi,
I've just found your post about Morrison ancestors in Dromore.
I also have that name and area in my tree, but they came from Fermanagh initially.
James Morrisson was my great grandfather, his father William. James was married to Mary Stewart, William to Lucinda Jennings. Mary died in 1903 and James married again. James worked in a cotton mill in County Down. Their daughter Madeline, my grandmother, was born in Dumbarton, Gilford, Co. Down.
Does this mean anything to you or am I just 'barking up the wrong tree'!?
