Hi Sarah
Thanks for your quick reply.
Unfortunately I don't know where Thomas Mackey and Bridget Remilton got married on 20 Jan 1854, it only had "Roman Catholic Church, County Kilkenny Ireland" as place of marriage on the birth registration of one of their children. They named their children Mary [Bridget's mother was named Mary Hanley], William, Thomas, James, Robert [Bridget's father was named Robert], Annie, Joseph, John and Patrick.
Thomas's father William Mackey was the one married to Honora Ryan in my husband's family tree. I estimate that as Thomas was born ca. 1826 that they would have been married sometime before that.
Kind regards
Helen
