For a sister: Clara, Audrey, Alice, Maria. These share Lillian's style and level of familiarity without rhyming or starting with the same letter.

It helps but is not required. Another Latin name (like Lillian) gets a small scoring bonus because shared roots read as deliberate, but a strong style match with Lillian matters more either way.
