Rabbi Nakhman Heilperin In the book Avodat Hamelekh by Menakhem Nakhum Kahane, published 1770 in Zholkva (download PDF), is a recommendation by Nakhman Heilperin “residing in holy community Visoki and the area”.
Notes: This may be the same individual as R’ Nakhman son of Simkha; perhaps Heilperin is another name he was known by.
