Good catch, Gadget! I’d say it’s him too.
But the first photo is not 1870s, the lady’s fashion is way out of date for the 70s. A photographic portrait was very much an occasion and any lady would be sure to be dressed as up-to-date as possible. The lady’s dress is late 1850s-early 1860s. Photo styles were changing rapidly around this time too, especially from glass to printed on paper, so that’s why we want to see the original if possible.
