I need help dating my rocking chair

I inherited this rocking chair from my great uncle. My mom tells me that it belonged to my great grandparents. She says that they have had it as long as she can remember, but we have no clue how old this rocking chair really is. I am curious about the style and approximate age of the chair. I have no clue where to even look for this information, so any information that I could be given would be excellent. The chair has printed leather on the back and the rest is made entirely out of wood. See the picture.
