Looking for Relatives

I am looking for assistance. My name is Joyce Forchuk (nee Donovan) from Alberta Canada.My ggg Grandfather John Donovan (O'Donovan) was born in the Kilkenny area about 1760-1765. His wife Catherine Wallace was born about 1765 in the Waterford City area. They were married about 1790. They had four children - Mary born in 1796 or 1797; Francis born in 1800; my gg GrandfatherJames born in 1805; and Michael born in 1807.The family imigrated to Canada, some info says in1820and other info says later in the 1820's. My gg Grandfather James was a school teacher in Ireland prior to immigrating. We have information about the family once they arrived in Quebec Canada, but mixed data on their prior information, as it was all "what someone said and was remembered". My husband and I are travelling to Ireland for a 10 day bus tour on April 10 2020. We plan on spending 5days in the Kilkenny/Waterford area once the bus tour is over and prior to us travelling back to Canada. We contacted a local genealogist and she commented that there were over 2500 Donovan families in the Kilkenny area. She also noted that the possiblity of John's father's name being Francis because their oldest son's name was Francis may mean somethingas well.We hope to be able to possibly connect some sort of family link on our trip.
