Lookng for Lyons and O Shea Families IN Cork

Hi,

I'm looking for members of the Lyons and O'Shea families in Cork. My Great Grandfather, William Lyons, born 1859 in Cork, married Mary Ann (O') Shea in Cardiff, Wales on 23 March 1880. Mary Ann was the daughter of William Shea and Johanna (maiden name not known) who was born in 1834 in Cork. William Lyons'father's name was Thomas whom I believe was from Cork.

Many thanks.

Tim Lyons
