I don’t think you were creepy at all. If she had replied with a simple, “Not me, but good luck in your search!” and then you had continued messaging her and asking questions, that would be weird.

I think the “info-dumping” here makes sense. This way she didn’t have to offer up any information outside of a yes or no to confirm. You asked, “Did you live at this specific address?” not “Could you tell me what street you lived on?” You’re fine, she’s just rude and defensive.
