John Costello and Mary Davey were married on 29 January 1859 in Kilshalvey , Kilturra RC Church.
I have copy of their marriage cert. Witness were Pat Davey and Mary Costello.They had 9 children: Catherine, Hugh, Michael,Mary, Eleanor, Martin, Patrick, John and Thomas. I am descended from John Costello who emigrated to Australia. He went to Kalgorle Goldfields, made a lot of money , then went to Palmer river goldfield, lost a lot of money and finally settled in Kilcoy north west of Brisbane and had a small farm there of 160 acres, I have not found any information of John C and Mary Davey parents.
