Bowers Family Organization? How does Maria Bowers tie into the family?

This is only one piece of paper which we found, but looks like there used to be a Bowers Family Organization. It looks like there were more pages. One of the individuals listed, Maria Bowers, is the one I do not know how she links to the family. Listed below is how the others tie into the family tree and who they are descendants of:

Raymond Cottrel Bowers - Louis James Bowers Sr.
Eugene Sanders Bowers - Frank Bradley Bowers
Junius Dewitt Bowers - Leo Fullmer Bowers
Audrey Marie Bowers Arthur - Charles Ernest Bowers
Ruth Pixton Bowers Robertson - John David Bowers

Do you know who Maria Bowers is?
