You are missing the point here, we are looking for evidence about a linguistic Greek minority in Macedonia, in other words evidence that supports there is a linguistic minority of this kind, not documents that don't evidence this linguistic minority. 

 In the meanwhile I found the book Bernard Comrie - The World's Major Languages Second edition published in 2009 by Routledge 2 Park Square, Milton Park, Abingdon, Oxon OX14 4RN ISBN 0-203-30152-8 Master e-book ISBN and under the Greek language chapter page 347-373, and mainly 19.2 Greek in its Geographic and Social Context there is no reference of Greek language minority in Macedonia. 
 Please point out some relevant evidence that supports there is this kind of minority thank you.
