old chair

I brought this rocking chair to Canada with me from New York. It was given to my Grandmother circa 1910, but not new at the time.
The cane seat has been replaced with wood, and one rocker has been repaired. It has provided good service to my family. I love the graceful lines of this chair.
Does anyone have any information about this design, or a suggestion of where I should look.
I would hate to it to finish its days in the recycle bin.
