John Kielty, County Clare, married Margaret Barry, County Cork. John emigrated first to Pennsylvania and in 1847 Margaret emigrated with John, age 5 and Johanna, age 2, (leaving baby Margaret with a relative) and Margarets 17 year old brother, John. Margaret died on board ship and was buried in a mass grave in Canada (place not known). John Barry brought the children to their father. John Kielty had his married sister raise the children even though he later remarried. His son John died at age 9 after falling from a tree. Johanna is my great grandmother. Any information would be appreciated.
