I am searching for John Alfred Coghlan, Charles Francis Coghlan, and Rose Coghlan. They were all born in Dublin, Ireland and immigrated to New York some time before the Civil War. A sister, Mary, stayed in Ireland. John Alfred joined the Union Army and was stationed in South Carolina where he married and stayed. I am a decendant of his. I do not know where the others went and would appreciate any information about them (ancestors or decendents). I have just started my research.
