hi
I've just just been browsing this site and think that I've got answers to the O'Grady/Dooley/Ryan conundrum. My data generally fits with information provided by you and is as follows:
Back in the day, A Margaret Sweeney married Patrick O'Grady from Kyle, Ballaghmore. They had 9 children for which I have records, one being James born 1884. A sister, Margaret, born 1880 married James Ryan. Margaret Sweeney had a sister called Catherine who married John Dooley from Butterisland near Coolrain, Co Laois. Ballaghmore, Butterisland and Borris-in-Ossory are all quite near each other.
I hope this will be of assistance to you.
