Calling all Family Members, Near and Far

Who is this?

I've asked this question before, but since then I have developed a few obvious clues that might help you to determine who is this mystery woman?

First, if you look in the lower right corner you can see a signature, it says, "JM Elliott." Some research tells me that JM Elliott was the photographer and the JM Elliott Photography Studio was in Columbus, Ohio around the late 1800s, early 1900s.

Second, judging from the hairstyle, my guess is that this picture was taken circa 1920.

This image came from my father's home, and no one is certain who it is. If we were of the thought that this picture is a direct ancestor, then our guesses are very limited. By the 1920s most of my ancestor's were living in Bucks County, Pennsylvania. I would think Columbus, Ohio, would be quite the excursion for a portrait studio.

Geographically, the closest family member to the studio would be my Great Grandmother, Elizabeth Missouri (Noll) Keckler. In 1918, she married and became Elizabeth Missouri Seilhamer, her approximate age would have been between 32 and 42 in the 1920s. Although, even she lived about 320 miles from the photographer's studio (using Google Maps and modern day interstates to navigate the distance).

Do you know who this is? Do you have any suggestions for me to research further to find out who this is?
