Who are these people?

This photo is from the collection owned by the late Mary Virginia Switzer of Fountain County, Indiana. I can't determine the age of the photo; the people look to my untrained eye as belonging to the first half of the nineteenth century. It's also difficult to gauge the age of the subjects. Are they in their 40s? 50s? Older than that? Does the woman appear to be younger than the man? 

I wonder if they are David White, Sr. (ca. 1777-1851) and his second wife Jane (1799-1858). I can't say for certain that the woman looks 20 years younger than the man.

It would help in dating the photo to know when Hayes' Gallery and Short's Block existed. It'd also help to be able to date the style of clothing they're wearing. Can anyone help? 

Thanks, Karen!

Wanted to give a shout out to Karen Zach, the intrepid administrator of the Fountain County, Indiana GenWeb site, for being so kind as to link to this blog. Thanks very much, Karen!

Fountain County was settled by families from Clermont County, Ohio, including my 3g-grandparents, Alexander and Hannah White, who moved there in late 1836 or early 1837. If you have Clermont County ancestors you should look in Fountain and neighboring counties for their descendants.

If you don't already know it, the Fountain County GenWeb site is a rich source of information very regularly updated by Karen. She and her platoon of volunteers are constantly collecting, transcribing and adding source material to the site. Check it out!
