Noble, strong, or hill; often a modern combination name.
Brealyn is a modern American coinage, likely created by combining the Irish-derived prefix 'Bre-' (from Brianna or Bridget) with the popular suffix '-lyn'. As a derivative of Brianna, it carries the Celtic meaning of 'noble' or 'high'. It may also be viewed as a variation of the name Braelyn, which has roots in the Welsh word for 'hill'.
