Big Tim, I have no definite proof one way or the other that McCorley was a presbyterian. I was always told that he was by old neighbours of ours in Newbridge, about a mile from Toome. Their families have been there for generations while I was only there for 6 years and was really young at the time. I have however been back in Toome dozens of times since and as I hope to be in Toomebridge this coming May I will see if I can find out anything more about this subject. I am sure the local historical society will have some information.
It is interesting to read the responses about him, everything from a convert to catholicism, a rebel turned outlaw etc.

I have just finished a wonderful little book " Episodes and Anecodes - Ulster in 1798". by Robert Young. This book contains details of an interview (given verbatim) between Reverend Classen Porter of Larne who interviewwd a James Burns in 1863. James burns (a weaver) participated in the battle of Antrim and Randalstown. He was also present with McCracken and others after the battle when they had retreated to Slemish, just before McCracken was arrested on his way to escape. His accounts about the battle of Antrim and Randalstown are very detailed but nowhere in the whole interview does he mention McCorley. Which leads me to believe that Rody may have been just a follower and possibly a highwayman later. The McCorley name is considered a catholic one but so is McCracken and Henry Joy was definitely a presbyterian. I will let you know if I find out anything more about him, The little book by the way was published by Davidson Books, Broomhill Road, Spa, Ballynahinch, Co. Down,
