For years, I have been seeking data concerning my grgrandfather who was born and lived in County Clare. I do not know his first name but I understand he and his family lived in Kilmurry. He had a son, John Birmingham, who was born about 1807. John was a tailor. He emigrated to the USA and sent back to Co. Clare for his mother, Honora, amd his siblings, Jennie, Julia, George Patrick, John, Elizabeth, Nora, rosdy. Margaret, Frank and William. They settled in Batavia, Genesee County, New York. John married Mary O'Leary from Tipperary. I would greatly appreciate any details about his Irish origins and any recommendations for an Irish researcher.
