Sorry for delay, just busy busy this week! Dont know much about Eugene Carroll, I'm trying to find out more about him myself. He was married to Joanne Smith, his daughter Sarah is my line, she was married to William Neill and they lived on Carrigoona Commons/Glencormick but she married my gt gt grandfather,George Doyle in 1881. I cant find him anywhere either if anyone has any ideas? Good luck with your search!
