Hickey, Mills, Murphy

Hello,  I am searching for descendants of sisters Anne, Eliza and Kate Hickey all born in Kilkenny between 1866 -1874; father's name Michael (Mich) Hickey. The sisters moved to Cork and are on the 1901 and 1911 census.  Anne Hickey married Thomas Murphy in Cork in 1905. (Anne's daughter Mary is my maternal grandmother; she was born in Clonmel in 1893.) Kate married John Valentine Mills and had two daughters: Kathleen Josephine and Georgina Alma.

I will be visiting Ireland this October and will be staying in Kilkenny, Clonmel and Cork to research further. I would be grateful if anyone has any information at all to help with my research.  Many thanks.  Viv Clarke
