Mystery Monday – Who Is Edna?

Update 3/14/2015:
While searching Ancestry.com, I discovered a picture of Edna Reiber on her wedding day. The picture is of a low quality and from a bit of a distance, but the similarities are enough that I believe it to be her. Edna Reiber is the sister-in-law of my 2nd great grand aunt Philamena Pepperney Reiber.
Original post:
This photo is from a collection of Lowry and Pepperney photos dating between 1915 and 1930. While the name ‘Edna’ is written across the top and bottom (more faintly), it’s not clear who Edna is. I have three Edna’s documented in my family tree and they are all on my maternal side, while the photo collection is on my paternal side. Perhaps over time I will find another Edna tucked in a branch somewhere.
