“Anabel Knight Powers Circa 1917” is the label on the back of this picture frame. A little research revealed only one Anabel Knight Powers in public documents. She was born in Texas in 1888 to William Knight and wife. She married John/Jack P. Powers in 1907 in Oklahoma. She lived apparently the rest of her life in Oklahoma and died there (McIntosh county) in 1972, ten years after her husband died.
I haven’t found anyone searching for Anabel or her family yet, but I will keep looking. It’s an absolutely lovely photo and comes in a beautiful frame. The picture, by the way, was framed in Houston, TX.
