What names go well with Oscar for a sibling?
For a brother: Vincent, Emmett, Calvin, Arlo.
For a sister: Molly, Mabel, Noelle, Vera. These share Oscar's style and level of familiarity without rhyming or starting with the same letter.

Does Oscar need a sibling name of the same origin?
Not really — Oscar's origin isn't recorded, so the score leans on style and sound instead, but a strong style match with Oscar matters more either way.
How is the match score for Oscar worked out?
Each name is checked against Oscar: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Oscar, sharing its "O" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
