Could somebody tell me which of the following sentences are correct?

I thought you knew who she was.
If the above sentence is correct, could somebody tell me why the following versions of a sentence exist?

i) Did you find out who she is?
ii)Dis you find out who she was?

Does it mean that if the situation is current, sentence i should be used and if the situation is a distance situation sentence ii should be used? How long the time is when we consider the situation is distance?[:^)]

It has nothing to do with the temporal distance of the situation. Normally, the dependent verb would follow the tense of the main verb, i.e. 'I found out yesterday who she was yesterday'.

You can see by my extension, however, that 'she' may well be the same person right now. If the condition still holds at the present, as you say, then the speaker/writer has the option of using either tense, depending on how s/he is viewing the situation at the moment of speaking/writing.
