Well 6 months later, I finally did! It had a 1961 brown patterned fabric.... I know it was 1961 because it had a tag on it, on the underside, complete with the name of the client it was custom made for.
I had several yards of this fabric left from an other project and decided it would be perfect for the rocker.... The Doilie (on the back of the rocker) was a gift from a wonderful friend and I just had to applique it on the chair..... I am happy with the rocker and will be putting it to good use tomorrow morning with my morning reading and tea.
