I would appreciate if anyone has the history book of Kletzk could
tell me if there is material on a Rabbi Moshe of Kletzk who lived
there probably during the latter part of the 18th century. The only
thing I know about him is that he had a son David who served as the
Rabbi of Novarodok during the 19 cent. Family names for Moshe nor
David are known.

Yes there is a lot of material, not only in the Yizkor Books but also in many Seforim. 
Rabbi Moshe Eisenstadt of Klekst was the son of Rabbi Michael Eisenstadt of Klekst the son of the Gaon Rabbi Meir of Eisenstadt, the "Ponim Mierot"
His son Rabbi Dovid Eisenstadt of Novordhok was a gaon and mechaber of a two volume sefer of Chidushim and teshuvos entitled Galia Maseches published in 1844, a few years after he was niftar I think in 1838.
Pages 20's -40 I think in the Pinkas Kletsk, Kletzk Memorial Book, E.S. Stein, Tel Aviv: 1959 contain many paragraph about all of these holy Rabbis and their descendants.
There is a paragraph or two about Rabbi Dovid Eisenstadt of Novardhok on page 25 -26 in the Pinkas Novarhok (Novarhok Memorial book), ed. E. Yerushalmi, Tel Aviv, 1963 
Among the descendants of the above mentioned are the Netziv of Volozhyn, Rabbi issur Zlaman Meltzer, Rab Elazar man Shach of Ponovich etc.
