Simplify the following text for a Grade 10 native English-speaking person.
Original: NÃ Dhoireann credits Kathryn Price NicDhÃ na with originating the term â Celtic Reconstructionistâ ; however , NicDhÃ na credits her early use of the term to a simple extrapolation of Margot Adler 's use of the term `` Pagan Reconstructionists '' in the original , 1979 edition of Drawing Down the Moon .
Simplified: She says she got the idea for the name from Kathryn Price NicDhÃ na , who had also written about it . Margot Adler 's 1979 book , Drawing Down the Moon has a chapter on `` Pagan Reconstructionists '' , and Kathryn NicDhÃ na says this is probably where she got the idea , even though the book does not mention Celtic Reconstructionists , just other kinds .
