Tiphanie. Saw it on a medical record. Also saw Crystal Glass. Not sure if birth or married name.
Grandma went by her middle name, which has been mentioned in this thread. Her true first name I've NEVER heard anyone else have. Started with a "W". I had a friend who had a membership to ancestey.com, and I had her look up the 1920 census for the county my grandmother lived in. That side of the family is German, so on the handwritten census, my grandma's given name starts with a "V". (W's are pronounced as V's in German for those unaware) My great-grandparents only spoke German, so I could totally see my grandmother's oldest sister (who would have been 12) translating. BTW, my grandma's sisters were Minnie and Ethel, while her brother was Ralph. I don't see any of those making a big comeback.
As "old" names go...I kinda like Meredith. Although, I don't know how old that can be considered.
