Old Wooden Rocking Chair

I purchased this from a lady whose mother passed, she said she believed the chair to be around 60 or 70 years old but wasn't sure. It has no markings that would explain the date or maker. The seat is made of four pieces of wood that are connected by pegs. Where the hands rest on the arm rests there are 2 lines cut out all the way around on each arm rest. Nails in it appear to be handmade.
