1990s model appendix bay mare NC

Looking for info on a fabulous mare I own. She is a tattooed bay Appendix with a star and snip. she was said to have been raced, then evented by a woman who probably attended Appalachian State in Boone, N.C. She gave the mare to a man who said he would keep her forever, you know how that goes…
She went by the name of Lee when I got her.
Her tattoo is barely legible, it is not jockey club, it seems QH racers have a different system.
I know this is a shot in the dark, but she must have had a lot of showing, maybe someone knows something?
