@runa1234 I appreciate you pointing out my mistake. could you please tell me how using 을 or 이 instead of 은 makes this sentence different ? these particles (은/는/이/가) are giving me a really hard time. I still don't fully understand them even though they're the most basic part of korean language.
@hawk- Sentences with 이/을 means you can't or don't remember her name, but 은 sounds like you remember all other things about her except for her name, emphasizing the fact that you don't remember just her name.
