Mary Ahern was the daughter of Micky Denis Ahern and Honoria Larkin of Tournafulla Limerick. She married Phil Barry of Toureendarby, Newmarket in Cork. She was born in the 1850s or 1860s.
I don`t know if she continued to live in Limerick after her marriage or went to Newmarket.
Would be delighted to get any further research tips or share information with anyone engaged in similar research.
