I have no direct knowledge of the PA Clees family.However, there is a Clees family buried in the Erie County, New York area.In Addition I have been able to trace my Clees family (father and grandfather were from the Traverse City, Michigan area) to Perry, Michigan which is the central part of the lower peninsula.
The old stories in family say that my Clees family settled originally in New York.
It is not inconceivable that they first settled in New York and they split - some Clees family members going to PA and some to MI.
I would be interested in linking these various Clees families.
Also - there is a variant spelling of Clees.It is Cleese - and I have seen it within the same family.Siblings spelling it both ways.You may also want to check this variant spelling.
