I have a study on Patrick Shiel, Michael's nephew, which was done by a gentleman in Michigan. That was in early 1970s, and he was trying to find who Patrick's father was and where he was born. Most of my info on Michael comes from his notes as he thought by researching Michael he would come across answers to his questions on Patrick. Don't know how it came out. Do you know which of the siblings Patrick might have been born to?
