Catherine Shearers father was William Shearer and her mother was MaryAnn Clements. I dont have D.O.B for you but her father died around 1847 in County Armagh. Her mother died around 1845 in Belfast.
Catherine was born in May 1853 in Belfast. She married John Leonard on 30th April 1872 in Glasgow. John was born after April 1848 in Old Monkland Lanarkshire near Glasgow. They had 3 children; William, Leo and Catherine.
Catherine died on the 1st of Oct 1938 at 65, High St, Cowdenbeath, Fife.
I hope that this is helpful, if you need anything else, I am a descendant of Catherine's son, William.
