My Elizabeth Dixon was born about 1853 in Kildare going by her age on the 1901 Dublin census. Unfortunately I don't know anything about her parents or siblings or even where she was married. Her husband, John Carroll was a train driver in Dublin and when he died she ran a dairy in Drumcondra. I have tried for years to find out more about her but so far I have failed. I can't see any connection with your Elizabeth but I cannot rule it out. Sorry I couldn't be ore help.
