My gg grandmother was Johanna CONDON of County Cork. She was born around 1805. She and her husband Michael HALEY and two daughters Mary and Catherine emigrated to the US around 1830. They were first in New Jersey, then in Baltimiore, MD, later in Louisville KY, and finally ended up in Edgar Co. IL (Paris). They had twelve children, nine of whom survived to adulthood. I know nothing of her origins or parentage. She would be of an age to be a sister of your ancestor. Do you have any more about the family? If so, contact me at: daviddunn@earthlink.net.
Thanks!!
