Good Golly Miss Mollie...

Miss Mollie Johnson, Westminster, Maryland 
From the information I was able to dig up, (pardon the pun) Miss Mollie was a school teacher. She was born about 1857, and her given name was Mary E. Johnson.
Inscribed on the back of her picture is the message "To My Little Eddie."
Eddie was my great-grandfather John Edward Murray, born in 1871.
The little I know about schoolteachers back in those days consists of the facts:
Once married, female teachers were required to relinquish their jobs.
All teachers were expected to act as role models. They were to maintain proper decorum, both on and off the job.
Miss Mollie appears to be an attractive young woman, and I'll bet she didn't remain single (and therefore teaching) for long.
One thing about this photograph puzzles me though- She seems to be rather fancily dressed for the prim and proper times she lived in, and good God- she's wearing earrings!
