I have just come across your response to Myra Duffy's posting. I think we possibly have the same Great Great Grandparents & that your Great Grandmother Elizabeth & my Great Grandfather Thomas may have been brother & sister.
My Great Great Grandmother was Anne Dunne & she married Thomas Eighan (born Rochfortbridge) & sired my Great Grandfather Thomas Eighan who migrated to Australia & married Bridget Murray who was also from Co. Westmeath.
I have been doing Thomas Eighan/Egan family tree Ireland -Australia for a number of years & have nearly completed all the Australian descendents.
My records show that Thomas & Ann had 7 children My Great Grandfather Thomas was their fourth child & Elizabeth was the fifth child. This information regarding the number of children may not be correct as it was obtained by a researcher in Ireland & I haven't checked to find out if it is correct.
I would be very pleased to hear from you
