I've been trying to figure out if there's any information I could dig out of this photograph. Family lore says it's a photo of my great-great-grandfather. He's rather a man of mystery and this is one of our only leads on him. My great-grandfather (his son) was born in 1905 in Chicago. If it is a photo of my great-great-grandfather, I'd assume it was taken sometime during the Spanish-American War. We have a theory that he may have been a member of a Wisconsin regiment, but we're not completely sure.
I don't know anything about military uniforms, badges, etc, and I've struggled to find resources online.
Does anybody know how I could date, decipher, or figure out any information from this photograph?
There appears to be a resource for UK military photos where experts can help identify dates, regiments, and other information, but I've not found anything like that for the US. I'm sure that the right person could get some kind of info from this.
