Brodie/Sullivan
I think I may have tracked down Johanna O'Sullivan's baptism at St Mary's Church, Clonmel.
Father : John Sullivan
Mother : Mary Kelly
On 1/02/1829
Now not sure this is correct as Mary Sullivan's death certificate says that she was the widow of Daniel Sullivan (farmer), not John Sullivan.Daniel appears in Griffiths Valuation: off Hayward Road Lane, St Mary's Clonmel
