Was her character, Tracy, known to the viewing audience as Charlotte from the beginning? Or, was it revealed as a surprise to the audience in Peggy's murder trial? Everyone knew her as Charlotte when I watched Victoria Wyndham on GL.

That's an interesting question, and I wonder if its been discussed deep down in the GL thread in the forums. I know from reading of old synopses and hearing of old audio from the early 70s the whole Charlotte/Sara/Kit feud was pretty twisted but I think Wyndham was on AW by that point in time.
