Trying to locate " Adda " (santa clara)

Greetings I am trying to reconnect with an old friend who is named "Adda" her last name which I don't quite remember begins with the letter S She is mixed with Italian and Spanish,she is in her mid 40 's and has brown hair and brown eyes.
We were pretty close friends for awhile but we both got separated and I haven't seen or heard from her since.
She grew up in the area and spent alot of time out on camino Real at various hotels.
If anyone happens to know her would you please tell her that TIm is hoping to find her.
Thanks for your help.
