I have a Marcella BYRNE of WICKLOW who married a Matthew NOLAN of Co Carlow.... c1823. After marriage they lived in TROOPERSTOWN, WIC. Known issue: Owen b 1826, Ellen b 1831, Catherine [died in infancy] and Simon b 1834. Do you see any connection to your Byrne line? [Owen and Ellen migrated to Australia]. Simon, I think, remained in Ireland but his descendants scattered to Canada, America and Australia ... and one line remained in DUBLIN. Please contact me re the above if you see a connection...I'm happy to share what I have with you Mary Shortis shortis@spot.com.au
