Found Ring

[IHeartUGA]

OK, ladies, I need your help. I received an email tonight from a very nice lady who found an Alpha Gam ring in Orlando back in the mid 1980's and she's trying to locate the owner. She said she tried contacting the webmaster to no avail...so, I've decided to try and locate this lost sister.

The ring has "M.A. Roberts" 1964 engraved in it. Then, on one side of the ring, it has "MU" and on the other side "AB".

I've done the sister search to see find anyone with the maiden name "Roberts" and tried to narrow it down from there. I just don't know if the "1964" is her initiation year or her graduation year. I also don't know if the AB/MU are chapters, her big and little's initials, or what (I don't have a ring so I don't know the traditions).

Any suggestions? She's emailing me a picture tomorrow so I can get a better look at the engravings.
