For a sister: Lainey, Nora, Harper, Lucy. These share Mason's style and level of familiarity without rhyming or starting with the same letter.

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