For a sister: Hazel, Chloe, Leilani, Lily. These share Isla's style and level of familiarity without rhyming or starting with the same letter.
Does a brother or sister name need to match Isla?
Only loosely. A brother or sister name should sound like it was chosen by the same parents as Isla, not like half of a pair.

Names that rhyme with Isla or also start with "I" get fewer points here.
Does Isla need a sibling name of the same origin?
It helps but is not required. Another Scottish name (like Isla) gets a small scoring bonus because shared roots read as deliberate — 1 of the names on this page are Scottish too, but a strong style match with Isla matters more either way.
