Well, do you have anything on the Lingua Ignota of Hildegard of
Bingen?  I've heard it called the earliest known conlang, although
it's really only a partial relex.

Then there's the various philosophical languages of the 17th & 18th
centuries, particularly that one by that guy... I can never recall his
name...  Bishop John Wilkins.  I don't have any specific links, but
you should be able to find something online.

Well, there's M.A.R Barker (Tsolyani etc.) and Suzette Haden Elgin
(Láadan).  They're somewhat known, if not exactly household names.
And Loglan/lojban, if they fit in this category.  I mean, none of
these languages are exactly known by the general public, but they are
at least known in some detail by people other than their creators.
