Gretta Conroy and Nora Barnacle

I just came across an interesting correlation between the character of Gretta Conroy and Joyce's wife, Nora Barnacle (shown in the picture above). Both women were from Galway, both women lived with their grandmothers, both studied in a convent, and more importantly both knew a Michael Furey character. Like Gretta, Nora knew a boy as a young girl in Galway who died from illness named Michael, only in Nora's case Michael's last name was Feeney instead of Furey. The similarities between the two women are pretty astounding! Not sure that this means anything to the text itself but I thought it was pretty neat.
