No DOB, all I know is that he was an officer in the military and left Denmark about 1880. His son Seth was also in the military, and stayed behind. John and wife Anne emigrated to USA with my grandfather (William) when he was an infant - "in swaddling clothes". This information is part of my oral family history passed down - with no written documentary evidence at all. Any or all of it is possibly inaccurate. (But still a great story none-the-less).
