^01^1. (אבי הגר"א)
Shlomo Zalmen of Vilna born c.1695, Vilna, Lithuania, married Treina of Seltz, born c.1700, Seltz, Byelorussia, daughter of Meir of Seltz. Shlomo died Kislev 5519, which corresponds to late 1758, Vilna, Lithuania.
Treina: Daughter of Rabbi Meir son of Rabbi Benyamin Wolf of Seltz, near Grodno, Byelorussia.
^02^1.1. (הגר"א)
Eliyahu Gaon of Vilna born 1720, Seltz, Byelorussia, married (1) Khana of Keidan, born c.1724, Keidan, Lithuania, daughter of Yehudah Leib of Keidan, died 1782, Vilna, Lithuania, married (2) after 1782, Gittel Luntz, born Kelm, Lithuania, daughter of Meir Luntz. Eliyahu died 19 Tishrei 5558 (9 October 1797), Vilna, Lithuania.
^02^1.2. (אחי הגר"א)
Yissakhar Ber Klatzki born c.1721, married Malka Ginzberg, daughter of Asher Ginzberg and Yuta Klatzes. Yissakhar died 1807, Vilna, Lithuania.
^03^1.2.6.
Reizel Klatzki married Azriel Ziv, born c.1760, son of Gershon Mendel Ziv, ABD Birz. Reizel died 1833, Vilna, Lithuania. Reizel was the most probable link with the Ziv (Sieff) and Grad families, based on the tradition related to Lord Israel Sieff by his great-grandfather that he was descended from a brother of the Gaon of Vilna. Sieff recalled the name of the Gaon's brother as Joshua, which was probably a distortion of Yissakhar Ber.
Azriel: the most likely connection between the family of Lord Israel Sieff and Gershon Mendel Ziv of Rassein. There is a conflict in the sources with regard to the identity of Azriel's father.
^04^1.2.6.1.
Efraim Ziv born c.1782. Appears in three Prenumeranten entries in Ateret Shaul (S. Luria, Vilna, 1841) as the father of Yosef, David and Matityahu Ziv of Kroz.
^04^1.2.6.2.
Shlomo Zalmen Leib Ziv born c.1800. Name appears on the tombstone of his daughter Peena Grad. A Prenumeranten list in Lekorot Hair Rassein Urabaneha (M. Markovitch, Warsaw 1913) includes a Zalmen Ziv who may have been identical with Shlomo Zalmen Leib Ziv.
