To make it more clear, we could have him say: “Leia also struggled with family legacy.”
Here it is all laid out:
Luke: “What are you most afraid of?”

Luke: “Because you’re a Palpatine? Leia also struggled with family legacy.”
Rey: “She didn’t tell me.”
Luke: “Rey, some things are stronger than blood…”
Or, to make it clearer still, it could be “Leia also struggled with infamous legacy.”
