I think you are confusing Ballymoney and Monaghan with Ballymullan which is the townland in which Crawfordsburn sits. I have gone through Ballymoney, Co. Antrim, records and have not found the name McCleve. Do you have any documentation to support Ballymoney or Monaghan ? Where did the arly McCleve information come from ? Earl;y handwriting is often difficult to read and Ballymoney might have been mistaken for Ballymullan. I come from the Crawfordsburn area and am related to the McFerrans. The Lamb family was also local.
