My great great grandmother was Catherine "Kate" Leo and she was married to Edward Keough in 1870 at St. John's Limerick. She was 22 years old. Therefore she would have been born around 1848. Her address at the time of her marriage was Hogg's Lane. This is now known as Flag Lane, just off Broad Street, Limerick City. Her father's name was Michael Leo. She may have had a sister or sister in law named Julia Leo. Does any of this ring a bell?
