John Henry Key and family. The names are on the photo, but I can't read the mother's name on this computer. What a handsome family!
William Joseph Tatu family, 1899, on front porch of residence in Buffalo. They are descendents of Francois Xavoir Tatu, who left Doubs, Franche-Comnte, France, in 1833 to emigrate to the US. Wm. J. Tatu, here depicted, is the third generation of that move. The photo was taken June 1890. Aloysia ("Alla") Tatu was 20 years old in the photo.
Frank & Rillie (Swartz) Burgess family In Guthrie, Oklahoma about 1910. I'm pretty sure that's mom and dad, second and third from the left in the back, and all their children.
The John Ellis Basham Family taken circa 1897.
Names are on the photo itself.
