To accurately answer whether "they" left before "her," I need more context. Please provide additional information, such as:

• Who are "they" and "her"? Knowing the individuals or groups involved is crucial.
• What is the situation or event you are referring to? Understanding the context will help determine the order of events.
• Is there a specific time frame? Knowing the dates or times will clarify the sequence.

Once I have this information, I can provide a precise answer.
