Why don't you simply google the names of the schools and see what turns up? Even if names have changed (mine has!) there is very often a continuing interest in the history, old scholars etc., and a lot of information is archived. It will not be long before there is no one left who attended the school I went to, under its old name, but the archives from 1827 are still available. Would not cost anything and could produce something. Just tried Rastrick Grammar out of curiosity (absolutely no other interest!) and, if I needed it, there is a fair bit of information available.
