A variant or obsolete spelling of 'gardine' or 'garden,' possibly referring to an enclosed space or fortification in some contexts.
This appears to be a regional or archaic spelling variant of Middle English terms related to 'garden' or fortified enclosures, combining 'gard' (guard/protection) with a suffix suggesting an enclosed space.
English spelling was wildly inconsistent before the printing press standardized it—the same word might be spelled five different ways on a single page! 'Gardeen' is evidence of how fluid medieval English truly was.
