For a sister: Colette, Margot, Noelle, Sylvie. These share Louis's style and level of familiarity without rhyming or starting with the same letter.

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