The woman on the right is my great grandma, Johanna (Degroot) Popkes. She was born in 1872, but it’s hard to say her age here-so judging by the clothing, I’m guessing this was taken a little after 1900.
All I know of the other woman is that in the photo album her name is Aunt Zena.
The setting is somewhere in the Midwestern United States around Iowa. Since they are wearing nice clothes, my guess is that they’re on their way to some type of function.
