Mary Minnie Loader

I am curious about a photo of my g-grandmother, Mary Minnie LOADER, 
b. 1 Feb 1868, Iredell, Bosque Co, TX……..
daughter of Thomas Fletcher LOADER & Lucinda Elizabeth MARTIN
Mary is sitting on a pony in front of a home or building, constructed of concrete or
concrete block (at least, the base or porch) ……Out of sight, on the porch, is a wicker
rocker……the foot of a man can be seen behind the pony, which was probably, her
I am wondering if anyone knows any buildings of this kind, in Bosque Co, at this time
period…..I appreciate any help….
