I am glad that the info on Francis M, Benjamin Jackson was tied in with what you already had.
I got the obituary from the newspaper for my father which said that he was born in Richland county and was the son of John Alfred Coghlan of Ireland and Addie Elmore of Sumter county. She was born in 1859. Addie's obituary said that she was a native of Kershaw county and the daughter of Robert Elmore and Sara Bramblett. Addie Elmore had a brother, Robert Lee Elmore, that was born 6-20-1865 in Hamlet, NC. He married Adella Agnes Welsh who was the daughter of Mr. and Mrs. William Welsh from Ireland. I also found a Minnie Coughlan that married Lester P. Hopkins. Their son, Arthur R. Hopkins was born May 28, 1917 in Augusta, GA and married Marie Carter from Kingstree, SC. I had always wondered how they were related and it looks like it was on the Coghlan side. Do you have any info on her? I found a Minnie Coghlan on the Social Security index and it gave her location as Mississippi. I have the 1990 census for Richland county ordered and will check this out when it arrives. My birth certificate has Sumter on it but my oldest brother has Camden which makes it more confusing.
Thanks again for your help in trying to locate John Alfred. I am going to search the National Cemeteries as we were told he was buried in one but we don't know which one.
