I too have Kilmartin in my line originating in Drumcliffe & lower rosses point, Co Sligo. michael Kilmartin born 1859 was my great grandfather. He married Bridget (B.1865)and had 5 children Mary 1890 (my grandmother) Kate 1892, William 1893, Bridget 1896 & Ellen 1898. I have not been able to trace back further than my great granfather as yet & was interested to know if your Kilmartins are related to mine! Happy hunting
