Nechemiah Halevi Ginzburg of Dubrovna. Divrei Nechemiah [responsa, with Drushim based upon Chassidic concepts]. Volumes I (Even Ha’ezer) and II (Orach Chaim).

Married to the daughter of R. Chaim Abraham Schneerson, brother of the Mitteler Rebbe, the author was one of the prime disciples of the Baal HaTanya R. Shneur Zalman (his wife’s grandfather). Divrei Nechemiah is important for the scholarly exchange of correspondence between the Tzemach Tzedek and the author. The Tzemach Tzedek regarded the author as one of the foremost poskim of his generation and deferred to him many difficult questions of Jewish law. In his correspondence, the Tzemach Tzedek refers to him as “chassan dodi” the son-in-law of my uncle (see f. 31b of volume on Even Ha’Ezer). The work also contains supplements and omissions of parts of the Shulchan Aruch HaRav (see ff. 73-8 of volume on Orach Chaim). These supplements were later included in subsequent editions of the Shulchan Aruch. See Mondschein, Sifrei Hahalacha shel Admo’r HaZaken, p. 26. Bound in gilt-decorated velvet, Volume I was apparently the personal copy of the publisher, the son of the author. The marginal notes were clearly transcribed from the author.
