Hello! I am seeking info on James C. KERR, b. 1839 in Ireland, d. 1910 in Greenville, Mercer co. His wife was Mary G. O'REILLY b. 1846 in Canada, d. 1902 Greenville, Mercer co. Both of their sets of parents were born in Ireland. I'm wondering if anyone might have any idea when they immigrated, how, or where from in Ireland, or how I might go about researching this. Thanks! Any help would be appreciated. Susan - Billings, MT
